imported model creates extra domain

Hi,

I have a simple 3D model that I've exported from Solidworks as a Parasolid x_t file and the pulled the Parasolid file into COMSOL. I am having a meshing issue which I have tracked down to a "ghost" domain.

The model was imported using 1e-6 tolerance, solids, surfaces, check for errors and repair. Everything looks fine except that there is an extra domain that is not in the drawing.

Domain 5 appears as a domain in the materials list, however, I cannot select this entity in the drawing in Geometry 1. Also, Domain 5 is where the issue appears during meshing.

If I could select this "ghost" entity, I would delete to see if that helps.

Does anyone in the Forum have a guess as to what might be going on? Attached is the COMSOL file.

Thanks,

Art
