Hi. I performed 3D meshing with attached geo file, there exists very thin tetrahedrons which can be a problem in FEM simulation. (Not only the attached geo file...I tried many other models)
I tried several mesh options like Mesh.AllowSwapAngle, but the result was same. Also, the message " ~~ ill-shaped tets are still in the mesh" always appears even after the optimization.
I can't figure out how can I avoid this problem.
I used gmsh 4.4.1 window 64-bit version (the latest one).
