I need to inspect bad cells in a mesh, to find out which geometry is causing problems.
From the meshing log:
Checking final mesh ...
Checking faces in error :
non-orthogonality > 75 degrees : 3092
faces with face pyramid volume < 1e-13 : 0
faces with concavity > 80 degrees : 2
faces with skewness > 4 (internal) or 20 (boundary) : 0
faces with interpolation weights (0..1) < 0.01 : 3
faces with volume ratio of neighbour cells < 0.0075 : 19
faces with face twist < 0.005 : 182
faces on cells with determinant < 0.005 : 0
Finished meshing with 3298 illegal faces (concave, zero area or negative cell pyramid volume)
Finished meshing in = 5809 s.
Is there a recommended procedure to dealing with each of these type of illegal cells?
