A Geo Surface Contact is a General Geometry Contact which can analyze the contact between any kinds of geometries. The geometry can be a rigid body or a flexible body and they can have any kind of shapes. Geo Surface contact analyzes the all possible contact points and output the all useful contact information such as the contact point, contact force, contact direction, and penetration. If the action geometry is a sphere, Geo Sphere contact is recommended to analysis more quickly and accurately. To see about the Geo Sphere contact, click here.
