Hello
I'm investigating the Fluent *.msh mesh with polyhedra generated via Fluent tool from tetra mesh with prism boundary layer (which was originally generated by Ansys Meshing).
The format of the *.msh file is well-documented, so I made up a simple script to read and analyze the mesh.
The result that suprised me after I examined mesh faces, was that many polyhedric cells in the mesh had non-planar faces. As far as I understand, according to Ansys Fluent description, the mesh faces should be planar, or else how can the solver use such faces to compute fluxes?

May be someone have useful information on the subject?
