COMSOL - Create subdomain from an imported geometry
 

Hi,

The version I´m using is Comsol 4.0a.

I´m trying to create subdomains from a geometry created on Salome platform (linux) with .stl extension.

The geometry is solid and when I work with that in Comsol, it´s treated as one domain only. I couldn´t separate in more subdomains to create different meshes.

I could create a mesh, but since my geometry is too big, some parts are not refined enough. Then, I need to treat those ones as subdomain and refine the mesh properly.

Could someone help, please? :)

Thanks.

Update
 

Were you able to find a solution to the problem of creating a subdomain from an imported geometry? When I import the geometry it is a boundary only and I do not know how to make it a solid or subdomain.

I am currently facing the same challenge and would appreciate any feedback.
Thanks!
