I've been doing a motion analysis of a vehicle with tyres of Polyurethane on a sandy/rocky terrain. By default the materials available under the contact properties are aluminium, rubber, nylon, acrylic and steel. When I set a contact between the tyres and the ground, I have to set the properties of contact by myself which doesn't turn out to be quite accurate.
I wanted to know if there is any method to import different material properties under contacts in motion analysis.
