Add LohCG artificial compressibility & viscosity for constant-density flow
Features:
- Solves incompressible Navier-Stokes
- Stabilization for advection and divergence operators: artifical
compressibility + artificial viscosity
- Simplest method targeting maximum speed for constant-density flow
- Fluxes: damp2 or damp4 with 2nd or 4th order artificial viscosity
- Time stepping: explicit RK[1234]
Add asynclogic tests
Tested with
- inviscid quarter and full sphere
- Poiseuille
- lid-driven cavity
Convergence tested with Poiseuille: damp2+rk3:p=2, damp4+rk4:p=2.5.
