The Sphere To FSurface Contact generates a contact force between a FFlex body and a rigid body.
•The FFlex body is the base body of contact.
•The rigid body is the action body.
•The patch set of the base 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 action contact geometry is defined as a sphere and the base contact surfaces are approximated as multi triangular or rectangular patches according to the finite element as shown in Figure 1.
Figure 1 Contact geometry
Contact points
The sphere of action body is examined whether it is contacted with the base patches.
