The FSurface To Surface Contact generates a contact force between a FFlex body and a rigid body.
•The FFlex body is the action body of the contact and the rigid body is the base body.
•The patch set of the action contact surface must be defined before creating the contact.
•The patch set should be generated on the FFlex body.
•The contact force is generated with the compliance characteristics allowing to the penetration.
The base contact surfaces are approximated as multi-triangular patches and the action contact surfaces are approximated as multi-triangular or rectangular patches according to the finite element as shown in Figure 1.

Contact points
•The nodes of action patches are examined whether they are contacted with the base patches.
•And then, the lines of the action patches are examined whether they are contacted with the lines of the base patches.
•Finally, the nodes of base patches are examined whether they are contacted with the action patches. For more information, click here.
