Dear experts,
Recently I am using umesh，but the file generated by geom_mesh tool has only one region for the whole geometry, so I can’t set different materials for the geometry.
Could you please advise on how to correct these errors?
Thank you in advance!

Dear @dingyuan1991,
Could you let me know what CAD file format you have used with the meshing script?
Edit: Sorry, I haven’t noticed the attachment
The .stl format doesn’t have support for definition of multiple solids inside. When many bodies are exported into .stl, they are merged into a single body.
Also, some CAD tools perform a union operation for all bodies during export into some formats supporting definition of multiple bodies. FreeCAD, for example, does this with .3mf output.
Best regards,
Volodymyr
Thank you very much!
