FEM ConstraintForce

Description

This command applies a force of given value [N] to selected target geometry.

Usage

Applying a force to a face, line or point:

  • In FEM workbench, click on Constraint Force or select Model → Mechanical Constraints → Constraint force to open Force Constraint properties dialog.

  • 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. It 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 the dialog and create [ 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.
