Description

Applies a force of a given value [N] to the selected geometry.

Usage

  1. There are several ways to invoke the command:
    • Press the FEM Constraint force button
    • Select the Model → Mechanical boundary conditions and loads → Constraint force option from the menu.
  2. 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.
  3. Click on a face, line or point to which a force should be applied. The object will appear in the list of geometrical objects.
  4. Fill in Load [N] with a force value in [N].
  5. 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.
  6. Click OK to finish.

Notes

  • The defined force is applied uniformly to the 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.
