Farshad_Noravesh Member Farshad Join Date: Oct 2010 Posts: 76 Rep Power: 16	Hi, First of all: can rhosimplecfoam simulate NACA0012 at mach=0.8? why? second: please tell me the appropriate boundary conditions for pressure. ---------------------------------------------------------------- I also think that GAMG in openfoam has problems because it is the combination of AMG and GMG . I have not seen GAMG in any article. rhosimplecfoam uses GAMG alot. is this the problem that we can not get good results and it diverges? openfoam is great, we should only improve AMG and adaptive mesh refinement for this opensource code. It is really weak. How about linking Hypre,parametis,PETSc to openfoam? Kind Regards, Farshad
