# How to model relative friction in ansys (FEM software)

When you have friction between two surfaces, then u use the relative friction coefficient right. But how do i do that with ansys? I have put contact element between two different materials, but it doesn’t seems as I can use the relative friction in ansys. ...

This is the possibilities i seems to have if i want to set friction coefficient ..
