How to model relative friction in ansys (FEM software)

[Pellefant]

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 ..

Perhaps you missed the box named "Friction Coefficient" when you looked?!

 

[Pellefant]

Yes but above that box, it is a box that says material id, which means that i give a friction coefficient for both materials, which hardly is the same as the relative friction between two surfaces
