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.

Description

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

Usage

  1. 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.
  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. It 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 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.
