  The Multiphysics Object Oriented Simulation Environment (MOOSE) framework is
a high-performance, open source, C++ finite element toolkit developed at Idaho
National Laboratory. MOOSE was created with the aim of assisting domain
scientists and engineers in creating customizable, high-quality tools for
multiphysics simulations. While the core MOOSE framework itself does not
contain code for simulating any particular physical application, it is
distributed with a number of physics "modules" which are tailored to solving
e.g. heat conduction, phase field, and solid/fluid mechanics problems. In this
report, we describe the basic equations, finite element formulations, software
implementation, and regression/verification tests currently available in
MOOSE's navier_stokes module for solving the Incompressible Navier-Stokes (INS)
equations.
