I want to set boundary id on a geometry in gmsh and read it in deal.ii. I have done the followings:
1 . I have imported my geometry .STEP in gmsh.
2 . Assigned elementary tag and physical surface "name" in the geometry section,

You will generally want to use numbers instead of strings for the names. deal.II uses numbers, not strings, and doesn't know what to do with them.


3 . Meshed
4 . when this file is imported in gmsh, error pops up saying,"negative volume"

Is this in gmsh? Or did you mean to say deal.II?
