How to connect different meshes with INTER/TYPE2

Hello,

Here is my issue: I want to change the mesh of a given part of interest in my model (green). I re-meshed it and now I would like to manage the interaction between my new mesh and the coarse mesh (grey) of the parts in contact with it (cf. screenshot).

I have been advised to use an INTER/TYPE2 interface. I tried to implement it but I didn’t succeed.

Should I take my part of interest (green) as master surface (Surf_id)? The tool proposes to select it by elements/set/component. The “by elements” option only works with shell elements, that I don’t have originally in my model.

For the Grnod_id (S), the selection by nodes works.

Also, which parameters would you recommend for this INTER/TYPE2? (Are the 0: default values ok for this kind of application?)

Thank you for your help.
