Trelis crashes at mesh command

Trelis 15.1 is crashing when I try to mesh a 3D volume using tetmesh. See the attached jou file.

This issue was fixed in 15.2.

The journal file creates a non-manifold geometry that caused Trelis 15.1 to crash. Yes, it has been fixed in 15.2, but you may still get an error that the bounding mesh has an odd Euler characteristic. It seems that we sometimes incorrectly determine the mesh of the non-manifold geometry is invalid. We will fix this. In the meantime, your mesh is a valid mesh, so you can modify your journal file to add the “keep invalid mesh” command.

surface all scheme trimesh
volume 1 scheme tetmesh
set keep invalid mesh on
mesh vol 1
