The FCurve To FSurface Contact generates a contact force between FFlex bodies.
•The patch set must be defined before creating the contact.
•The contact surface:
•Must belong to a FFlex body.
•Should be two different patch sets.
•The contact force is generated with the compliance characteristics allowing to the penetration.
The base contact surfaces are approximated as multi triangular or rectangular patches according to the finite element and the action contact surfaces are approximated as multi cylinder and sphere in the line and node of the beam element as shown in Figure 1.
Figure 1 Contact geometry
Contact points
•As shown in Figure 1, the lines of action cylinders are examined whether they are contacted with the lines of base patches.
•And then, the action spheres are examined whether they are contacted with the base patches.
•Finally, the nodes of base patches are examined whether they are contacted with the action cylinders.
