Applied Force (Rigid Connector)
Use the Applied Force to apply a force to the rigid connector. The force can act at an arbitrary position in space, and if it is not located at the center of rotation, there is also a moment contribution. The force that you specify is interpreted in the selected coordinate system.
Coordinate System Selection
The Coordinate system list contains all applicable coordinate systems in the model. Select a Coordinate system for specifying the directions of the force.
Location
Select an option from the list: Center of rotation or User defined. This is the location where the force is applied.
For Center of rotation, the location of the load is taken as the center of rotation as defined in the parent Rigid Connector node.
For User defined, enter the Location (global coordinates), Xp, in the table.
Select the Offset check box to add an optional offset vector to the definition of the location. Enter values for the offset vector Xoffset.
The location used is the sum of the vector obtained from any of the input methods and the offset vector.
Applied Force
Select the Direction of the applied force — Space-fixed direction or Body-fixed direction.
For Space-fixed direction, the directions of the applied force F are fixed with respect to the selected Coordinate system.
For Body-fixed direction, the directions of the applied force F follow the rotation of the rigid domain.
Enter values or expressions for the components of the Applied force F. The direction coordinate names can vary depending on the selected coordinate system.
Linear Buckling
To display this section, click the Show More Options button () and select Advanced Physics Options in the Show More Options dialog box.
If you are performing a linear buckling analysis with a combination of live and dead loads, select the Treat as dead load check box to indicate that the load contributions from this node are constant. The default is that a load is proportional to the load factor.
 
You can add the Phase subnode to specify the phase of this load in a frequency domain analysis.
