NETGEN_3D Error

I have a problem to mesh my solid part with 3D automatic tetrahedralization.

I made solid part in salome (from step file imported from SolidWorks).

What could be the reason?

Thanks

Hi Kirill

A reason of netgen failure at 3D meshing is often a poor quality of 2D mesh, which in its turn caused by difficult geometry, e.g. by presence of narrow faces.

It is often possible to detect a reason of failure by analyzing the 3D mesh that was created anyway.

Hi Saint Michael.

Yes I realize what is the reason of the failure but I didn't understood what is the way to fix the problem.

Is it manipulation with the 2D mesh?

Thanks Saint!

It depends on a kind of problem. Some issues can be fixed by adjustment of local meshing parameters, others can be fixed by modification of 2D mesh before 3D meshing.

I repair it by using the "Shape Processing" tool... Is it good idea?

The manipulations with 2D and 3D mesh didn't help me...

Your idea is wonderful!
