Unphysical solution in simpleFoam due to meshing with SHM (I guess)

Hey all,
I try to simulate a radial impeller case with a cylindricalInletVelocity-boundary applied on a cylinder. In image 0 attached you can see the configuration of the stl-files. 0.jpg The simulation runs well with simpleFoam and also finishes with good residuals. During post-processing I recognised some singularities on the inlet which -as I mentioned above- is defined by cylindricalInletVelocity-boundary condition. 1.jpg With visiable mesh it seems like the pressure-"stripes" are caused by the mesh. 2.jpg I am usually working with openfoam 7 by openfoam.org. I also tried version 8 and v2006 by openfoam.com to rule out a version problem. Does somebody has an idea where this singularites come from? Thank you very much and kind regards! |
