Allowing slipping between internal boundaries in the Structural Mechanics Module

Hello
I have created a model with the following geometry: a square background (low stiffness) with an elliptical inclusion (high stiffness) using the union operation. By default, it is my understanding that COMSOL assumes no slipping is allowed at the boundary between the background and the stiff inclusion.
I want to allow slipping at the above mentioned boundary. Could someone help me out?
Thank you

Dear Vikram,
I would take a look at contact modeling, and a simple example is written out in "sliding wedge" from the model library.
In short, you set the geometry to be an assembly. Then create contact pairs, and use these in the physics.
If correctly set up, this will allow the parts to slide alongside each other.
Best regards,
Frank
