rhoSimpleFoam convergence
Giles Richardson
Have you got any advice or sample files (fvSolution, fvSchemes) for getting rhoSimpleFoam to converge please?
I'm running an aircraft case at Mach 2.0, using rhoSimpleFoam, with freestream BC in the far-field.
The whole solution becomes very oscillatory, even though initial convergence looks ok. I am using relaxation factors and limiters that have worked for me before. I have used rhoSimpleFoam many times before for supersonic applications, but this time I'm having difficulty.
