Hello everyone,

I am currently analyzing a complex geometry where the mesh structure is obtained by Hypermesh. I saved the mesh structure with .stl extension. However, I am confused on how to import it in Comsol.

My question is: How do I import this mesh structure to be able to analyze it in Comsol? Should I import this in the Geometry section or the Mesh section in Comsol?

In addition, when I want to give boundary conditions to this structure, I get the “Not Applicable” error. I cannot even manually select the region where I want to apply the boundary conditions.

I am attaching the error I got.

Could you please help me with this issue?

Kind regards,

Gokay
