  A stand-alone App has been developed, focused on obtaining information about
relevant engineering properties of magnetic levitation systems. Our modelling
toolkit provides real time simulations of 2D magneto-mechanical quantities for
Superconductor/Permanent Magnet structures. The source code is open and may be
customized for a variety of configurations. Ultimately, it relies on the
variational statement of the critical state model for the superconducting
component and has been verified against experimental data for YBaCuO/NdFeB
assemblies.
  On a quantitative basis, the values of the arising forces, induced
superconducting currents, as well as a plot of the magnetic field lines are
displayed upon selection of an arbitrary trajectory of the magnet in the
vicinity of the superconductor. The stability issues related to the cooling
process, as well as the maximum attainable forces for a given material and
geometry are immediately observed.
  Mainly, the purpose of this work was to provide a comprehensible data
processing tool that may be of help for analyzing the counter-intuitive, but
highly relevant, hysteresis effects that occur when the magnet wags around the
superconductor. It may be a resource for guiding discussions and physical
interpretations in Maglev design (as a complement to the dedicated computer
simulation tools). Also, to a large extent, it has a focus on enlightenment,
training and dissemination actions.
