FEM ConstraintForce/en

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

Usage
1) Applying a force in normal direction to a face
 * In FEM workbench, click on FEM_ConstraintForce.svg or select →  →  to open Force Constraint properties dialog
 * If you have Mesh displayed, you need to hide it (select the mesh object and press or right click and select ) and show the original model.
 * Click on a face to which a force should be applied. It will appear in the list of geometrical objects.
 * Fill in with a force value in [N] (attention: Not in [N/m])
 * : In a typical case, you'll click this field empty to apply a force in normal direction to the face. You can revert the direction of the force by clicking . In other cases, you need to pick a face or plane, which is in normal to the force direction (it could differ from the face, to which the force is being applied)
 * Click to finish the dialog and create  object

2) Applying a force in to line in selected direction
 * In FEM workbench, click on FEM_ConstraintForce.svg or select →  →  to open Force Constraint properties dialog
 * If you have Mesh displayed, you need to hide it (select the mesh object and press or right click and select ) and show the original model.
 * Click on a line segment to which a force should be applied. It will appear in the list of geometrical objects.
 * Fill in with a force value in [N]
 * : Now, with line segment selected, it si likely that the force is applied in a wrong direction. We need to specify the direction by clicking the button and then clicking a face pointing with its normal to the direction of the force (or reversed direction). Again, you can revert the direction of the force by clicking.
 * Click to finish the dialog and create  object
