Hi guys, the non-orthogonal

Hi guys,

the non-orthogonality is so great (almost 90 deg between the cell face normal vector and the displacement vector from owner to neighbour cell centres), because of the meshing strategy:...

checkMesh complains about 28 h

checkMesh complains about 28 highly skewed faces. Is that enough to upset the continuity (it's only 28 in over 7M faces). Perhaps I should give a try to skewLinear wherever linear has been used so...

Hi everyone, I am strugglin

Hi everyone,

I am struggling to get simpleFoam working on a purely tetrahedral mesh featuring anisotropic elements in the boundary layer (generated with Gridgen). I tried quite conservative...
