Ill tets with freefem
Hi Christophe,
I'm quite confused about the 3d mesh generated by gmsh, freefem stops and says the mesh contains "badly orienated tet" with very small (10e-18) or zero meseare in these cases :
-
optimize=0
gmsh log looks very fine -
optimize=1
i get a log with warnings about "ill tets" temp.log
I also set Delaunay Tolerance = 1e-12 as you adviced me.
Sometimes with clmax=1 i get a valid mesh, sometimes not... strange, is there a probabilistic aspect in mesh generation ?
