Detailed Description

template<class Viscosity>
class GRINS::IncompressibleNavierStokesBase< Viscosity >

Physics class for Incompressible Navier-Stokes.

This physics class implements the classical Incompressible Navier-Stokes equations. This is a templated class, the class Viscosity can be instantiated as a specific type (right now:ConstantViscosity or SpatiallyVaryingViscosity) to allow the user to specify a constant or spatially varying viscosity in the input file
