Automatic sizing refinement gets stuck

[m.d.stubbs]

Whenever I set the mesh parameters, the software gets stuck on the automatic sizing refinement. It loads to about 90%, but gets stuck and doesn't progress any further as seen on the image below. I don't know how to set up a manual mesh, so this halts my productivity quite significantly. I'm just looking for advice as to how to solve this issue.

Looks like your model may have some geometry issues.

Try taking it into a the geometry repair tab. or go into the cad model and make sure there are no flipped normals or unstiched edges.
