The FCurve To FCurve Contact generates a contact force between FFlexbodies.
•The patch set must be defined before creating the contact.
•The contact surfaces must belong to FFlexbodies.
•Two contact surfaces should be two different patch sets.
•The contact force is generated with the compliance characteristics allowing to the penetration.
The action and base contact surfaces are approximated as multi cylinder and sphere in the line and node of the beam element as shown in Figure 1.

Contact points
•The lines of action cylinders are examined whether they are contacted with the lines of base cylinders.
•And then, the action spheres are examined whether they are contacted with the base cylinders.
•Finally, the base spheres are examined whether they are contacted with the action cylinders.
