The Sphere To FCurve Contact generates a contact force between a FFlex body and a rigid body.
•The FFlex body is the base body of the contact
•The rigid body is the action body.
•The patch set:
•Of the base contact surface must be defined before creating the contact.
•Should be generated on the Flex body.
•The contact force is generated with the compliance characteristics allowing to the penetration.
The action contact geometry is defined as a sphere and the base 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
The sphere of action body is examined whether it is contacted with base cylinders and spheres. And then, the action sphere is examined whether they are contacted with the base spheres.
