BFGS update error2 ???

I am concerned about the mesh that results in a case where the ref. error is displayed.

In the attached file, in the screen oiutput section:

Note that after several announcements of “start tetmeshing”, success is declared.

A couple of lines below, the ref. error is displayed.

Upon manually loading the resultant mesh (gui), I notice differences in node and element counts.

Key question: Is the mesh a good mesh? When I ask netgen (gui) to check the mesh, I did not detect a response.

if you load the .vol-file into netgen-gui, you can select “Mesh” → “Mesh Quality” and you will obtain minimal/maximal angles, which shall be bounded away from 0 and 180,
