MRFSimpleFoam - Influence of Solver Settings

Hi there,
I was just doing the axialTurbine_mixingPlane tutorial for the MRFSimpleFoam solver (foamExtend 3.2) and found out that the final result (eg. total pressure loss and torque on the runner blade) is very sensitive not only to the interplotation schemes but also to the relaxation factors. If I increase the relaxation for velocity the torque increases. Besides, the residuals of the tangential velocity always remain on a high level and I can't push them down. Does anyone have experience using the MRFSimpleFoam solver and maybe had the same problems? I would appreciate any hints! Best regards, Julian |
