Applied Force (Rigid Domain)
The Applied Force subnode is t is used to apply forces on a rigid domain. The force can act at an arbitrary position in space. A force implicitly contributes also to the moment if it is not applied at the center of mass of a rigid domain. The force that you specify is interpreted in the selected coordinate system.
Location
Select an option from the list: Center of rotation, Centroid of selected entities, 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 Domain node.
For Centroid of selected entities select an Entity levelBoundary, Edge, or Point. The available choices depend on physics interface and geometrical dimension. The force acts at the centroid of the selected entities, which do not need to be related to rigid domain itself. As a special case, you can select a single point, and thus place the force at that point
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
Enter values or expressions for the components of the Applied force F.
You can add the Phase subnode to specify the phase of this load in a frequency domain analysis.
