AutoBush FD

Connections define the two connecting bodies, the point where the forces act, and the marker that defines the bushing orientation. Bodies, markers, and points can be selected either graphically or through the Project Browser.

1. From the Connectivity tab, select the first body to connect.
   The I marker of the Force_field statement in the solver deck lies on Body 1, is located at Point 1, and has the orientation of Marker.
   • Click Body 1 and select a body from the modeling window.
   • Double click Body 1 and select the required body from the dialog.
2. Similarly, select the second body to connect by clicking the Body 2 input collector.
   The J marker of the Force_field statement in the solver deck lies on Body, is located at Point 1, and has the orientation of Marker.
3. Select a marker to orient the bushing in space.
   • Click Marker and select a marker from the modeling window.
   • Double click Marker and select the required marker from the dialog.
   All three axes of the bushing are along the axes of the respective axes of the Marker (X-X,Y-Y,Z-Z).
4. Select a point to locate the bushing. The point defines the location where the bushing forces act. The I marker and the J (floating) marker of the Force_field statement are at Point 1.
   • Click Point 1 and select a point from the modeling window.
   • Double click Point 1 and select the required point from the dialog.
5. Check the Output box to write requests into the solver deck that request the force in the bushing, the displacement across the bushing, and the relative velocity across the bushing.
