The FSurface To FSurface Contact generates a Contact Force between FFlexbodies.
•The patch set must be defined before creating the contact.
•The contact surface must belong to a FFlex body.
•Two contact surfaces should be two different patch sets.
•The contact force is generated with the compliance characteristics allowing to the penetration.
The base and action contact surfaces are approximated as multi triangular or rectangular patches according to the finite element as shown in Figure1.
Figure 1 Contact Geometry
As shown in Figure 1, the nodes of the action patches are examined whether or not they are contacted with the base patches.
And then, the lines of the action patches are examined whether or not they are contacted with the lines of the base patches.
Finally, the nodes of base patches are examined whether or not they are contacted with the action patches.
