INSStressComponentAux

INSStressComponentAux calculates the stress (component) for an incompressible Navier-Stokes simulation. Specify the comp param (allowed values 0, 1, 2) to obtain the desired stress component. Note that the velocity parameter expects a non-vector variable, e.g. this AuxKernel only currently makes sense with the hand-coded set of INS objects.

This class computes the stress component based on pressure and velocity for incompressible Navier-Stokes
