Process gmsh meshes in CGX

Gmsh-generated meshes need to be converted before use in CCX:

• Boundary regions are written as sets of surface or line elements and associated node sets.
• Frequently, you need element face based surface definitions in CCX

Conversion procedure in CGX. In the example we have a second order tetrahedral mesh with a physical surface in called "load". Upon export to inp, CPS6 elements are created along with a corresponding node set.

Read the mesh

read gmsh.inp

Delete the surface elements. Use the generic element-type based set created by CCX upon reading the file.

zap +CPS6 

Expand (complete) the existing node set to include also the associated element faces

comp load do  

Then you can use that set to write surface definitions
