Hello SimScale Staff,
for cfd calculations with medium to high turbulence flow a polyhedral mesh would reduce cpu time and costs.
A nice comparison of hexahedral-, polyhedral- and tetrahedral mesh was created by Symscape.
Polyhedral, Tetrahedral, and Hexahedral Mesh Comparison
In OpenFOAM a tool named polyDualMesh is integrated. It converts a tetrahedral- into a polyhedral mesh.
At OpenFOAMWiki i found an article about the workflow
Polyhedral mesh generation
I think it would be a nice feature for more experienced cfd user and every case with complicated domain would benefit from shorter cpu time.
Last but not least the tool is integrated in OpenFOAM.
