Issue with SRFSimpleFoam
Dear developers,
I am running a benchmark OpenFOAM case to compare its results with a reference run performed with Starccm+, adopting the same polyhedral mesh. The steady-state case involves the impeller of a centrifugal pump and the mesh includes just one blade and conformal periodicity surfaces. Boundary conditions have been imposed to be coherent with the ones of Starccm+. The solver adopted is SRFSimpleFoam.
The problem is that the case seems to converge in less that 3000 steps, but the results that I get are totally surrealistic. Just to give you an idea, the pump is predicted to work as a turbine with static pressure reducing its value moving downstream in the meridional flow-path. Also the pressure field has a range spanning from really low to really high values.
I tried several settings in terms of fvSchemes and fvSolution without any improvement.
As I am not sure what is the exact issue afflicting the run (cyclicAMI, SRF model, etc.), I have uploaded all the case on Dropbox, you can find the link here: link
I hope you can find a way to fix the solver behavior for this case, thanks in advance.
