How can I simulate the friction between a floor slab and a foundation without having to enter a contact solid?


When entering a surface elastic foundation, you can set the nonlinearity for the spring stiffness in the direction of the local z‑axis. For example, "Failure if negative contact stress."

In the detail settings for the nonlinearity (a button to the right of the nonlinearity selection), you can select the "Friction in plane xy" option. Furthermore, you can also enter the friction coefficient.
