2D Mesh - Multibodies

Hi,

How can I make the mesh in the interface region? I need the elements and nodes in the interface are coincident.

Thank you.

HyperMesh

Just split surface of the 1st by lines of the 2nd.

Share your model?

How can I do this?
My model is attached.

Thank you.

Make 2D mesh on 1st solid (yellow) => Make 3D tet mesh for 1st solid

On interface, make 2D mesh on 2nd solid => Equivalence of nodes.

Make the rest of 2D mesh of 2nd solid & equivalent of nodes:

Finally fill 3D tet for 2nd solid and get the final result:

HTH,

The same method but with hex mesh:
