3DynaFS-VIS - Viscous Module

The 3DynaFS © viscous module solves the incompressible Navier-Stokes equations using an artificial compressibility method. The solution procedure can be marched in pseudo-time to reach a steady-state solution or can use a dual time-stepping scheme to obtain a time-dependent solution. The code uses a first-order Euler implicit time-difference scheme, a third-order accurate flux-difference upwind splitting scheme for convection terms, and a second-order central differencing for the viscous terms.
