•Definition of the Base Surface
•Entity Name: Defines the name of base surface. The base surface is dispatched from the screen by clicking Gr.
Figure 2 Preview of the normal directions, contact patches and boundary box
•Normal Direction: Is the normal direction of base surface 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: Allows you to access the dialog box of Contact Surface. For more information, click here.
•Definition of the Action Flexible Surface
•Entity Name: The name of action patch set. The action patch set can be dispatched from the screen by clicking Gr.
•Normal Direction: The normal direction of action 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: Allows you to access the dialog box of Contact Surface. For more information, click here.
•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.
•Use Node Only: Only nodes of the action surface are examined in searching a contact point. Generally, this option can be very useful for accuracy and solving speed as will be observed in the following case.
o If the user does not use this option, the contact is applied as patch shape only.
o If the user uses this option, the contact is applied as flexible body shape more correctly.
•Smooth contact: Is to use the curve surface on an action patch set. So, if this option is used, contact is continuously applied on Flexible surface.
•Force Display: You can graphically display the resultant force vector on the view window. For more information, click here.
•Refresh: When the action patch set or base contact surface is changed, you can refresh the preview of information of specified contact patches set as using this function.
