•Definition of the Base Flexible Surface
•Entity Name: Defines the name of the base patch set. The base patch set is dispatched from the screen by clicking Gr.
•Normal Direction: Is the normal direction of base patch set for a contact. 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.
•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 base 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: Nodes of base flexible contact surface are only used to generate the contact force of Sphere To Fsurface contact. 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 base patch set. So, if this option is used, the contact is continuously applied on the flexible surface.
•Definition of the Action Sphere
•Entity Name: Defines the name of action patch set. The action patch set is dispatched from the screen by clicking Gr.
•Radius: Is the radius of action sphere. This value is automatically determined by the radius of the action geometry but if you turn off the Synchronize with Geometry option, you can directly input the radius or change it as the parametric value by clicking PV.
•Synchronize with Geometry: If this option is checked, the contact radius of circle or sphere is automatically defined with that of the specified graphic.
•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 information of specified contact patch set as using this function.
