Description
This command applies a force of given value [N] to selected target geometry.
Usage
- There are several ways to invoke the command to apply a force to a face, line or point:
- Click on
FEM Constraint force button
- Select the Model → Mechanical Constraints →
Constraint force option from the menu.
- Click on
- If you have Mesh displayed, you need to hide it (select the mesh object and press spacebar or right-click and select Hide item) and show the original model.
- Click on a face, line or point to which a force should be applied. The object will appear in the list of geometrical objects.
- Fill in Load [N] with a force value in [N].
- Direction: In a typical case, you'll leave this field empty to apply a force in the normal direction. You can revert the direction of the force by clicking Reverse direction. In other cases, you need to pick a face/plane or edge, which serves as reference for force direction.
- Click OK to finish and create the
ConstraintForce object.
Notes
- Defined force is applied uniformly to selected objects. For example, if you define one force constraint with 200 N applied to two faces having the same area, each face will be uniformly loaded with 100 N.
