Applied Force (Rigid Material)

The subnode 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.

Coordinate System Selection

The list contains all applicable coordinate systems in the model. Select a for specifying the directions of the force.

Location

Select an option from the list: , , or. This is the location where the force is applied.

•

For , the location of the load is taken as the center of rotation as defined in the parent node.

•

For select an — , , or .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.


	Once chosen, a default Location: Boundary, Location: Edge, or Location: Point subnode is automatically added.

•

For , enter the ,Xp, in the table.

Select the 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 of the applied force — or .

•

For , the directions of the applied force F are fixed with respect to the selected .

•

For , 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 button (

) and select in the dialog box.

If you are performing a linear buckling analysis with a combination of live and dead loads, select the 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.


	For more information about live and dead loads, see Buckling Analysis.

•

You can add the Phase subnode to specify the phase of this load in a frequency domain analysis.

•

You can specify this load to be a Harmonic Perturbation in a frequency domain analysis.

•

You can assign this load to a load group. See Load Cases in the Structural Mechanics Modeling chapter.
