What is a Mesh?

Per definition, a mesh is a network that is formed of cells and points. It can have almost any shape in any size and is used to solve Partial Differential Equations. Each cell of the mesh represents an individual solution of the equation which, when combined for the whole network, results in a solution for the entire mesh.

Solving the entire object without dividing it into smaller pieces can be impossible because of the complexity that is within the object. Holes, corners and angles can make it extremely difficult for solvers to obtain a solution. Small cells on the other hand, are comparably easy to solve and therefore the preferred strategy.

Brief History

The history of the mesh and meshing techniques is closely related to the history of numerical methods. The paper by Courant, Friedrichs and Lewy1

 is arguably the fundamental starting point for the Finite Differences Method (FDM), where concepts such as the C.F.L. (Courant, Friedrichs, Lewy) stability condition were introduced.

Historically, rectangular and Cartesian grids are associated with the Finite Differences, due to the easy identification of point neighbors, used in the derivatives approximations.

The Finite Element Method (FEM) allowed for mixed types of mesh cells, and unstructured meshes became feasible. Variational formulations being used to solve problems numerically can date back to Lord Rayleigh and Ritz works, from the end of the 19th century to the first decade of the 20th century2

The first steps for numerically solving a set of partial differential equations (PDEs) is the discretization of the equations and the discretization of the problem domain. As mentioned earlier, solving the entire problem domain at once is impossible whereas solving multiple small pieces of the problem domain is perfectly fine. The equations discretization process is related to methods such as the Finite Differences Method, Finite Volume Method (FVM) and Finite Element Method, whose purpose is to take equations in the continuous form and generate a system of algebraic difference equations. The former, namely the domain discretization process, generates a set of discrete points and cells that cover the continuous problem domain.

A mesh is, by definition, a set of points and cells, when connected to form a network. This network can have many forms of geometry and topology, as will be discussed later. Often, meshes are also called grids, and that is generally related to the intrinsic organization of the mesh and/or when those meshes are related to Finite Differences problems.

Each cell or point of the mesh will hold a local solution of the equations, depending on whether the equations were discretized over the cells or points. The choice whether to discretize the equations over the set of cells or points is a project decision, and many aspects can affect the choice.

In general, point discretization is used when the equations are approximated using the Finite Differences Method, where the PDEs are usually approximated by Taylor series expansions at each point’s neighbors. Sometimes the point discretization can be used together with the Finite Volume Method, however, cells are going to be implicitly used around points.

When the equations to be discretized are considered in the weak form, integral form, or conservative form, it is common to solve the integrals over discrete cells. For example, when considering transport phenomena, the Finite Volume Method can be formulated as the discrete cells representing small volumes. Then, the fluxes can be balanced through those cells, while supposing that the solution is constant inside them.

cell solutions

Mesh Types

It’s common to classify mesh types as being structured (curvilinear) or unstructured3

. As discussed before, structured meshes are historically related to the Finite Differences Method. The Finite Volume and Finite Element methods’ nature allows for more general meshes.

Structured Meshes

Structured meshes, also commonly called grids, are meshes whose structure and formation allow for easy identification of neighboring cells and points. This property is derived from the fact that structured meshes are applied over analytical coordinates systems (rectangular, elliptical, spherical, etc.), forming a regular grid.

From a programming point of view, the cells or points that form a structured mesh can be enumerated in such a way that neighboring queries can be made analytically upon the cells or points coordinates.

Consider the mesh from the picture below. Its first cells are enumerated, along with the first four left and right boundary cells. This mesh is an example of a rectangular mesh. To illustrate the ease of obtaining cell adjacencies, it’s clear that to obtain the right adjacency from any cell, the problem is reduced to summing one to its enumeration. Similarly, the top adjacency from any cell is obtained by summing nine to the cell enumeration. This allows for each mesh element to be mapped directly to an array or vector, making computations easier.

mesh enumeration example

Figure 3: Mesh enumeration example

Any curvilinear grid can be mapped to such coordinate and neighboring system. Therefore, from a programming standpoint, there is little to no difference between a curvilinear grid and a rectangular grid in terms of adjacency queries.

rectangular and curvilinear grid

Figure 4: Mapping between a rectangular and a curvilinear (cylindrical) grid

Structured grids might also be defined in terms of boundary fitting. For example, a cartesian grid fits the boundary of a rectangle, and the cylindrical grid fits the boundary of a cylinder. It’s possible to mix the boundary fitting and have many different curves or surfaces that define the boundary. These include any kind of parameterizable curves and surfaces, such as splines and NURBS (Non-Uniform Rational Basis Spline). The meshing algorithm will decide how points will be distributed through those surfaces, and how opposing surfaces will be connected to each other, given how many points should be created for each curve or surface.

Unstructured Meshes

Unstructured meshes are more general and can arbitrarily approximate any geometry shape. In contrast with structured meshes, where the coordinates and connectivities map into the elements of a matrix, unstructured meshes require special data structures, such as an adjacency matrix or list and the node coordinates list. The unstructured mesh node/cell numbering can be arbitrary and sparse since it does not require any analytical form of adjacency query.

unstructured mesh and adjacency list

Figure 6: Example of unstructured mesh and its adjacency list

Complex geometries that would be impractical to generate a structured mesh within, can be discretized using unstructured meshing techniques. The flexible nature of unstructured meshes allows various cell types to be used and coexist in the same mesh, making it possible to have an even better geometry fitting and overall element quality.

Cell types can be separated into 2-Dimensional cells and 3-Dimensional cells. Common 2-Dimensional cell types are the triangle and the quadrangle. Common 3-Dimensional cell types are the tetrahedron and the hexahedron but might also include the pyramid and wedge. These cell types form what is sometimes called the finite element zoo since these cell types are commonly used with Finite Element schemes. Finite Volume schemes are known for being more flexible in terms of the cell types being used, sometimes allowing for any kind of polygons and polyhedra.

2D and 3D cell types

Figure 7: Common 2-Dimensional and 3-Dimensional cell types

Mesh cells are not required to be conformal. Nonconforming meshes are those where hanging nodes occur. These nodes appear more commonly during mesh adaptation processes.

Figure 8: 2-Dimensional mesh with a hanging node

Mesh Adaption

Since on unstructured meshes the points and adjacencies do not follow any kind of global structure, it is also possible to add or remove mesh cells and points. The process of dynamically adding, removing or displacing mesh cells and points is called mesh adaptation.

Depending on the problem nature, mesh adaptation techniques are required to obtain accurate solution fields while maintaining the computational cost of the problem low, by keeping the overall number of mesh cells and nodes under control.

In general, the degree of refinement required is associated with the error, which is estimated based on the equations to be solved. Therefore, regions with higher error will end up accumulating more mesh cells.

Mesh refinement is divided into several general types. Most commonly, these types are referred to as h-type, r-type, p-type, derefinement, and combinations of those.

Mesh Refinement and Derefinement

Mesh refinement, which is also called h-type refinement, is based on the addition of cells or points, reducing the local characteristic length of edges. This technique can cheaply increase local mesh resolution, but will also increase the number of simultaneous difference equations to be solved, since it increases the number of degrees of freedom of the system.

On unstructured meshes, the addition of cells or points is straightforward, as it involves the reconnection of the modified cells. Refinement on structured grids isn’t straightforward since the addition of cells could break the mesh regularity. It’s common to allow for nonconforming meshes when using adaptive structured grids.

h-type mesh refinement

Figure 9: Example of h-type mesh refinement

SimScale mesh refinement example

Figure 10: Mesh refinement example of a product simulated with SimScale

Similarly, mesh refinement techniques, in general, allow for mesh derefinement, which can be used to decrease the number of cells in regions where the estimated error is very low. This allows for computational power to be more efficiently used, reducing costs and simulation time.

Mesh Movement

Mesh movement, or r-type refinement, is done through the movement or displacement of mesh cells and points. In this case, the number of cells and points remains constant, while also sometimes keeping the connectivity the same.

Below is depicted an example of an r-type mesh refinement process that could be related to a shock wave propagation problem, for example, where the mesh resolution is kept higher in regions of high variation on the solution.

r-type mesh refinement

Figure 11: Example of r-type mesh refinement

Other Mesh Adaption Techniques

Other common mesh adaptation techniques might include p-type refinement and adaptive remeshing. On p-type refinement, which is associated with the Finite Element Method, the complexity of the shape function is increased, while keeping the same mesh. The adaptive remeshing technique is used to generate a new mesh, based on the estimated error. This allows for the best overall mesh quality, and fewer points to be used. On the other hand, the overhead of mesh creation might be large. Adaptive remeshing can be used locally, generating new meshes only on regions where the estimated error is too high or low.

Combinations of the aforementioned techniques can be used. For example, the combination of r-type and h-type refinement can be referred as rh-type refinement, where nodes can both be displaced or created on the mesh.

Meshing and SimScale

SimScale provides a rich set of meshing algorithms and mesh types, together with comprehensive tutorials.

Ocean temperatures hit record high off San Diego, another extreme weather milestone

Doyle Rice
Surfers leave the water next to Scripps Pier Thursday, Aug. 2, 2018, in San Diego. The Scripps Institution of Oceanography says it has recorded the highest sea-surface temperature in San Diego in its 102 years of taking measure.

By East Coast standards, a water temperature of 78.8 degrees isn't all that toasty. But it was an all-time record for the Pacific Ocean near San Diego last week.

Scientists at the Scripps Institution of Oceanography have measured the ocean temperature at a pier in San Diego for 102 years – and on Friday Aug. 3, it was warmer than any other time on record.

It was yet another extreme temperature record for a planet that's seen a slew of them this summer, from 90 degrees north of the Arctic Circle in Finland to a possible all-time record high for Africa of 124 degrees, among many others.

Researchers at Scripps said the record warm water is consistent with similar records for high temperatures set on land this year.

It's also how global warming will play out, they said. Records related to heat and intense weather will become easier to break, having been given a boost from man-made climate change, which has added about 1.8 degrees to ocean temperatures over the past century, according to Scripps.

More:Global heat, fires and floods: How much did climate change fuel that hellish July?

"Like other climate change trends, background warming enhances the probability and magnitude of extreme events," said Scripps oceanographer Reinhard Flick.

It's not only the water near San Diego that's been warm: The ocean region off Southern California has been experiencing unusually warm temperatures for the past week and other stations farther off the coast have also reported record or near-record temperatures.

And we can't blame El Niño. The natural El Niño climate pattern typically inflates near-shore ocean temperatures, but the most recent one ended in 2016, and the sea water has remained warm.

Usually, ocean water temperatures return to historical averages following an El Niño, but that hasn’t been the case this time, according to Scripps physical oceanographer Dan Rudnick. “It looks like we took a step up during 2014-2016 from which we have not completely recovered,” he said.

Friday's record temperature broke a record that had been set only two days earlier, when the mercury hit 78.6 degrees. Prior to that, the warmest reading was 78.4 degrees, set in July 1931.

The daily Scripps pier temperature reading of the Pacific ranks as one of the world’s longest ocean time series, and is the longest on the Pacific Rim.

    plz send details at idpssmartsolutions@gmail.com


Hi! My name is Michael Grindheim, CEO of Frozen Moment Photography. I became fascinated with photography at a very young age. Born in Ukraine, and orphaned at the age of two, I was adopted at the age of seven, by a family here in the states. Overwhelmed by all this family had to offer, I remember being most impressed with their Polaroid camera. I was completely fascinated when my mom took a photo, and within seconds the print came out and I was able to see the image. From that moment on, I always thought of photography as a kind of magic. Adding to that, years later, being able to recall important times and people in my past because of the images made by that magic Polaroid, photos soon became a vital part of my life. I'm convinced that without those pictures, some of my important memories would have been lost forever.

My love of photography continued into my teen years, and through hard work and perseverance, I was finally able to buy a camera of my own. I found myself taking photo after photo, one never being enough. This is when I learned there was so much more to photography than "Point and shoot". I began to realize that I could also show my creativity through photography. Some people create using instruments, or art media, I create frozen moments in time, through the lens of a camera.

Photography, can also tell a story. I have learned to preserve God's handiwork on glossy paper. Like others, I often get caught up doing, going, or running somewhere. But photography is where I find peace, and an opportunity to get closer to God. I have spent hours shooting the night sky, where God's beauty shines. His art is all around us, but sometimes we don't notice it until we see a still photo. Thanks to photography, we can marvel over it, preserve it, and share it with others so that they, too, might be as blessed as the one who captured it.

My goal:

 To provide you a wonderful, happy, successful photo session, without all the stress and hassle of trying to do it yourself. In your busyness, don't fail to take time to preserve your important moments, flying by at warped speed. I would love to give you those one of a kind shots, that will preserve your memories for a lifetime, or longer; memories you will be proud to share with friends, neighbors, and more importantly, generations to come.

Good, the Bad and What Is Quantum Mechanics

The Fundamentals of What Is Quantum Mechanics That You Will be Able to Benefit From Beginning Today

An increasing number of scientists become involved with this area of research and study. Put simply, ozessay.com.au/term-paper-writing-service/ potential energy is energy that may get kinetic energy later on. The theory was hailed among the 20th century’s best achievements.

Once more, classical physics couldn’t explain the photoelectric effect properly. Computer simulations of a number of the experiments are available also. http://www.unm.edu/features/2011/trail-of-time-illustrates-geologic-splendor-of-grand-canyon.html Choas theory uses mathematics to inquire into the dynamics of systems that are highly vulnerable to the debut of conditions making outcomes seemingly not possible to predict.

Watching a quantum system evolve in time is a rather effective technique to become familiar with the basic characteristics and peculiarities of quantum mechanics. In other words, the engine employs quantum shortcuts to reach a state that is generally achieved solely by slow adiabatic processes. Now consider the exact same experiment on a significantly smaller scale.

But the calculations get the job done. These correlations violate a sort of Bell’s inequality that was obtained by a comprehensive set of measurements. In this, they is viewed as a tool rather than a theory.

But students from backgrounds apart from physics may discover that it’s quite hard. We just made up energy to create the math simpler. Basically, a Quantum computer is quite a strong computer.

The What Is Quantum Mechanics Pitfall

The measurement of A cannot be utilized to instantly transmit any form Custom Essay Help of other info to B at great distances, and nobody observing B will have the ability to tell independently whether or not A was measured. Negative thinking will entice negative outcomes. While the experiment is fundamentally the exact same but for the size, we’ll demonstrate how the outcome is quite different.

Some people are only hopeless. You may start to appreciate the chance that awareness doesn’t end with death. Among the most controversial issues concerns the function of measurements.

The Definitive Strategy to What Is Quantum Mechanics

While there’s general agreement that information plays a part in all that happens in the cosmos, it’s still a minority view that it’s more fundamental than physics. The rules simply don’t jive with our knowledge of earth. If 3-D has no reality, it doesn’t have any structure and substance, then any extra dimensions equally does not have any reality.

In reality, force is this kind of understandable notion we often neglect to ask what force is or if there might be a better approach to speak about the world. There are several poor pilgrims who aren’t able to afford to pay. The truth is quite a few respected scientists are starting to believe our universe couldn’t have been created without outside guidance.

Personally, it’s only efforts in this direction that have claimed my energies. There’s an additional consequence. It’s far deeper than thata awareness of interconnectivity between all things.

Classical systems may also be correlated, obviously, but this is different. As a way to perform such a job, several theoretical tools are revised in a preceding step. Companies like Lockheed Martin, set a wonderful deal of work into ensuring that aircraft system software is accurate.

It too is quite a tough text, but it’s a lot more complete than Sakurai or almost any class. As a consequence, the material becomes repelled by the external field. The majority of these books proved too difficult following a few pages, or so the range of posts for them is quite limited.

Just make sure that you do the appropriate conversions. Be aware this isn’t superconductivitythis is a standard circuit, with resistance. Entanglement will get stranger still for systems that have many components.

The high degree of the lighter region gets less far away from the middle. At a specific channel width, the flow becomes congested. A biochemcial cell’s membrane is currently believed to function as a semi-conductor.

The imagined listener might be a spouse, it could be Jesus or Buddha or it could be no one particularly. If you’re not able to grasp the subject of the discipline, then you ought not elect for it otherwise you won’t have the ability to write on it. Neutronic matter is quite dense indeed.

Top What Is Quantum Mechanics Choices

A wormhole connects two points in space via a kind of tunnel through a greater dimension. If an additional position measurement is created shortly afterwards the wavefunction will nonetheless be the very same as when the very first measurement was made (because nothing has happened to change it), and thus the very same position is going to be recorded. You’ll also learn the way the equation may be used in a variety of applications including quantum dots and vibrating molecules.

The two particles are not really permitted to get any closer. A wave function may also describe a system of several particles. Theory of Super strings also contributes to the spin 2 particles referred to as GRAVITONS.

Can residential locksmiths solve problems with access control systems in Hospices?

Before we plunge into any other details, let us first analyze what access control systems are. The access control systems, as the denomination suggests, is a lock system that restricts the number of users who can gain access through it in a computing environment. Essentially, there are two distinct varieties of access control systems; one is the physical control that allows ingress into the corporeal spaces such as college, school and office campuses and other IT estates. The second kind is logical control that allows access only to system files and data and computer systems. Several reasons have led to the popularity of access control systems in modern times. To begin with, we must acknowledge the simple user interface that it comes with. Long gone are those days when one worried about storing their keys safely in the pocket and then making a duplicate copy of the same to be used when the first batch is lost or misplaced. Furthermore, owing to the property of its limited access, and by linking them to some other security appliances of the apartment, one can keep a record of the number of people moving in or out throughout the day. Now, addressing the primary question of whether or not the residential locksmiths can solve problems related to access control systems, we would say that the answer depends on their expertise. Several reasons accompany this statement of ours.

Firstly, the residential locksmith who has been endowed with the responsibility of repairing the access control system should be acquainted with its various mechanisms that are commonly used in homes and offices. They should be efficiently trained to open and formulate all the inputs from distinct brands and with methods to ensure the reincarnation of the lost safety. Most of the residential locksmiths are familiar with the traditional lock and key that requires a single entity to initiate the entire procedure. The types and initial processes might seem different and require distinct approaches, but should be addressed with sufficient knowledge and technique. The disclaimer that must be probed with some significant consideration is that if something goes wrong inside the access control system, it can encounter a permanent lock leading to graver complications.

Secondly, when it comes to repairing the access control systems, residential locksmith should be well equipped before getting started. The pattern and instruments that go into the digital locking systems are quite distinct from its contemporary. There are a lot of inevitable steps that lead to the shielding of these systems; starting from its detection to identifying the areas that require attention, it all adds up to create the enhancement of the security measures. When you get in touch with a professional locksmith, make sure that he carries out a short survey of the site and then diligently assesses all the safety emblems associated with it. With all these measures duly taken into account, get in touch with your nearest residential locksmith to get your access control system repaired now.

A Hospice Social Worker

A Hospice Social Worker

You might have scratched your head several times thinking and wondering what a Hospice social worker does. Understanding the unique they provide is like taking a step closer to humanity. So, without further expansion of thought, let’s get into learning all about these individuals.

Job Description

The role of a Hospice Social worker is to advocate a patient’s last wish and help them further advance such aspects during the last stages of their life. Apart from that, they also play a crucial role in assisting families in getting the necessary treatment and service in the way of gaining additional support. Their jobs involve talking to people during their very last moments, and that is not easy. The services that they grant can never be identified in terms of value as you can only feel the experience.

Crucial Aspects

Hospice Social Workers maintain a specific moto when they go in for work, and that is to ensure that certain aspects are covered through their shift. They work on a basis to find and explore the most critical element to the patient or the thing which affects them the most. These are individuals who spend a lot of time listening to their patients keeping in mind the betterment of their progress.

The Required Support

The place and surrounding which these individuals work in cannot be predicted. The thought process that people go through at moments when they realise that their loved ones will be leaving are feelings that you cannot explain. Their minds might be blank, heavy with sorrow and a lot more goes into making them smile again. So during such moments Hospice workers tend to provide the necessary support which will help you get back to reality. They are experienced individuals who make things easier for you even when situations are hard.

Under One Roof

Under One Roof

Hospice workers tend to bring the entire family together during such critical aspects of life. They try to achieve this by giving everyone a take on reality and helping them come to terms with what has happened. Hospice workers have their way of dealing with such situations, but they never leave unless and until they have achieved what they came for. There might be numerous factors which prevent such last meetings, but they go all out in ensuring maximum satisfaction and progress.

The Last Right

By now, the family is quite aware of what is going to happen and will be ready to face such situations with the required help. But when it comes to matters such as last rights or the final death, they leave it to the members of the family to decide. A good death is one which your loved ones want for you, and they ensure that this is satisfied.

‘When I first walked into Ellenor Lions, I expected nothing, as I was completely clueless. But today, I sit here facing the world only because of what they have given me, and I will always be grateful.’

Melanie O. Kenny

‘My daughter always uses the best words to describe the experience she had at Ellenor Lions, and she fumbles at the thought of literature”.

Baby miracle testimony:

Back in July our friends Mike and Karen asked us to pray for baby Collin. After some difficulties during child birth, Colin had just been born with severe complications. He was born with blood on his brain, and struggling to breath/survive. His life was in serious danger with talk of not making it or at a minimum, they said he would likely have brain damage.

We prayed one Saturday while on the streets with our prayer team including several other days with Laury and I individually declaring that the baby would recover fully with no side effects, in the mighty name of Jesus. In fact, there were a whole lot of people offering fervent prayer on behalf of baby Colin and his mother. . This was him in the beginning.

Colin Before Prayers

But almost immediately, prayers were answered and Collin started to quickly improve. Within a couple weeks he was feeding normal, and off the respirators and feeding tubes. The term kept coming up “miraculous” with the doctors and nurses and Collin was called the “miracle baby” when he was released with no ailments, no brain damage, and perfectly healthy on August 13th. To God be the Glory! Amen

This was Collin when released: Yay God!

Why We’re Not Keen On Lindsay Corporation’s (NYSE:LNN) 2.1% Return On Capital

Simply Wall St

Today we'll look at Lindsay Corporation (NYSE:LNN) and reflect on its potential as an investment. In particular, we'll consider its Return On Capital Employed (ROCE), as that can give us insight into how profitably the company is able to employ capital in its business.

First up, we'll look at what ROCE is and how we calculate it. Next, we'll compare it to others in its industry. Finally, we'll look at how its current liabilities affect its ROCE.

Understanding Return On Capital Employed (ROCE)

ROCE measures the amount of pre-tax profits a company can generate from the capital employed in its business. In general, businesses with a higher ROCE are usually better quality. Overall, it is a valuable metric that has its flaws. Renowned investment researcher Michael Mauboussin has suggested that a high ROCE can indicate that 'one dollar invested in the company generates value of more than one dollar'.

How Do You Calculate Return On Capital Employed?

Analysts use this formula to calculate return on capital employed:

Or for Lindsay:

0.021 = US$8.6m ÷ (US$506m - US$87m) (Based on the trailing twelve months to May 2019.)

So, Lindsay has an ROCE of 2.1%.

See our latest analysis for Lindsay

Does Lindsay Have A Good ROCE?

One way to assess ROCE is to compare similar companies. We can see Lindsay's ROCE is meaningfully below the Machinery industry average of 12%. This could be seen as a negative, as it suggests some competitors may be employing their capital more efficiently. Independently of how Lindsay compares to its industry, its ROCE in absolute terms is low; especially compared to the ~2.7% available in government bonds. There are potentially more appealing investments elsewhere.

Lindsay's current ROCE of 2.1% is lower than 3 years ago, when the company reported a 6.7% ROCE. So investors might consider if it has had issues recently. The image below shows how Lindsay's ROCE compares to its industry, and you can click it to see more detail on its past growth.

Remember that this metric is backwards looking - it shows what has happened in the past, and does not accurately predict the future. ROCE can be deceptive for cyclical businesses, as returns can look incredible in boom times, and terribly low in downturns. This is because ROCE only looks at one year, instead of considering returns across a whole cycle. Future performance is what matters, and you can see analyst predictions in our free report on analyst forecasts for the company.

How Lindsay's Current Liabilities Impact Its ROCE

Lindsay has total liabilities of US$87m and total assets of US$506m. As a result, its current liabilities are equal to approximately 17% of its total assets. This is a modest level of current liabilities, which will have a limited impact on the ROCE.

What We Can Learn From Lindsay's ROCE

While that is good to see, Lindsay has a low ROCE and does not look attractive in this analysis. You might be able to find a better investment than Lindsay.
