Detailed Description

Implements artificial viscosity and heat flux for the 5 moment Euler/Navier Stokes equations.

This model uses artificial heat flux (H) on the shock/contact discontinuities and artificial viscosity (Q) on the rarefaction wave.

Parameters

Fluid	fluid variables
FluidGradient	Gradients of fluid variables (currently must be LDG gradients)
gamma	gas gamma
mass	species normalized mass
multiplier	Constant multiplier which scales all heat flux/viscosity coefficients by. Usually this will be 1, however in some cases there may be some geometric factors to take into account due to how WARPXM computes an effective dx vs. how the method expects and effective dx to be. This method expects the effective dx to be the n-th root of the element volume, where n is the number of dimensions.
EtaScalesWithDX	true if this method should make the eta jump discontinuity penalty parameter be inversely proportional to the effective dx. Recommended that this be false for LDG (default).
