GINA Mesh for different zones

Hello everyone!
I use GINA to build a geometry and also a mesh.
My mesh is divided into 2 zones. I also defined the surfaces. I wand to have different meshes for the zones.
How can this work with GINA?
I try to create a mesh in this way:

Mesh → Meshing → Create Mesh from Geometry → Quad → unselect delete Geometry → exit (after that step i can not see the geometry in the viewer).
If i try to refine the mesh i cannot select in which zone i wand to to this.

Can someone help me?

Thank you! :slight_smile:
