            The Contacts panel allows you to specify the attributes of a contact force between two bodies. Each body is represented by a set of graphics entities. The graphics entities could be a point, a set of curves, or the outer surfaces of the bodies depending on the type of contact that is chosen.

          • Rigid to Rigid Contact

            A Rigid to Rigid contact captures contact forces between two rigid bodies moving relative to each other in either a 3D frame or a 2D plane.

          • Flex Contact

            MotionSolve supports contact between a flexible body and a rigid body or another flexible body. The method to add such a contact to a model is the same as a Rigid to Rigid Contact and uses the same panel as the contact between rigid bodies.

          • Point to Deformable Surface Contact

            A Point to Deformable Surface contact can be used to model contact between a point on a rigid body and a deformable surface. When the deformable surface is defined on a surface of flexible body, this entity can be used to model contact between a rigid body and a flexible body. The contact is specified at a certain radius from the point. As a result, the contact is essentially between a sphere represented analytically and a deformable surface.
