[Gmsh] Intersection between 2 tetrahedral meshes

[Octavio Castillo Reyes]

Dear all,

I'm trying to build a tetrahedral mesh from 2 meshes with a complex
vertical surface.  I have managed to build the meshes independently,
however, I have no idea how to do the intersection operation between them.

My final goal is to build a mesh where both materials can be identified
(please see the attached image). Can you provide me with details and tips
to face my problem? Which could be the best strategy?

Best regards

O.
