Definition of the Action Surface
Name: Defines a surface as an action geometry for the contact.
Normal Direction: Defines the normal direction of action surface for a contact as shown in Figure 27.78.
Node Contact: If this option is checked, then the node contact of the action surface is considered. It is helpful when the action surface is smaller than a track link.
