Contact type

      What contact type is suitable for a sliding joint and a hinge joint?


      I want to give a constraint in patellofemoral and tibiofemoral joint.

      Frictional contact is suitable for either type of motion. The shape of the contact faces determines whether the motion is linear or rotational. You use frictional contact when you are interested in detailed stress in the faces making contact.


      In models where you are not interested in the detailed stress in the faces making contact, then you can choose to simplify your model by replacing the frictional contact with a Translational Joint or a Revolute Joint.
