invalid mesh in paving clean up

Coreform Cubit Meshing
#1

Hi,

I am trying to get a very fine mesh surface with pave scheme. When I set the surface size to be 1, it works well. But when I set the surface size to be 0.5, it shows “invalid surface mesh found in paving clean up”. It sounds strange because I didn’t change anything except the surface size.

Any help will be appreciated.

Thanks!

Trelis reports this error when bad connectivity is found in the paved mesh during clean-up. The paver may have created the invalid mesh or the clean-up routine may have corrupted the mesh.

Although, the paver should be deterministic when given the same size, changing the size may give an entirely different path through the code. Changing the size of the mesh slightly may yield a valid mesh, in this case, either 0.49 or 0.51.

we are currently working on finding and fixing the underlying problem.
