•     Definition of the Base Flexible Surface

•    Entity Name: The name of base patch set. The base patch set can be dispatched from the screen by clicking Gr.

Figure 2  Preview of the normal directions, contact patches and boundary box

•    Normal Direction: The normal direction of base patch set for a contact as shown in Figure 2. For more information, click here.

•    Preview Contact Surface: If this option is checked, the patches making the contact surface and its boundary box are highlighted on the screen as shown in Figure 2.

•    Contact Surface: Accessing Contact Surface dialog. For more information, click here.

•    Ref. Frame for Contact Surface: The contact force applied on the base body is reported as a force generalized on the defined marker. If the marker is not defined, the default is Ground.Inertia Marker.

•     Definition of the Action Flexible Curve

•    Entity Name: The name of action patch set. The action patch set can be dispatched from the screen by clicking Gr.

•    Preview Contact Surface: If this option is checked, the patches making the contact surface are highlighted on the screen as shown in Figure 2.

•    Contact Curve: Accessing Contact Curve dialog box as shown in Figure 3.

o  Cross Section: The cross section of beam patch set. The cross section is a circle.

o  Radius: The radius of circle. The radius of cylinder and sphere of the contact geometry is determined by this value.

o  No. of Divided Cubic Cell: The number of cubic cells dividing a contact boundary box. This value is automatically calculated. But if need be, the value can be modified by user.

o  Update Position of Contact Nodes: A flag whether the position of nodes belong to the patch set is updated during a simulation. If your system is the small deformation problem and this option is off, the solving time can be improved.

•    Ref. Frame for Contact Surface: The contact force applied on the action body is reported as a force generalized on the defined marker. If the marker is not defined, the default is Ground.Inertia Marker.

•     Force Display: You can graphically display the resultant force vector on the view window. For more information, click here.

•     Refresh: When the action or base contact patch set is changed, you can refresh the preview of the information of the specified contact patch set as using this function.
