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 Constraint Force or select ModelMechanical ConstraintsConstraint 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 to which a force should be applied. It will appear in the list of geometrical objects.
    • Fill in Line load with a force value in [N] (attention: Not in [N/m])

    • Direction: 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 Reverse direction. 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 Close to finish the dialog and create FEM ConstraintForce.png ConstraintForce object


2) Applying a force in to line in selected direction

    • In FEM workbench, click on Constraint Force or select ModelMechanical ConstraintsConstraint 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 line segment to which a force should be applied. It will appear in the list of geometrical objects.
    • Fill in Area load with a force value in [N]
    • Direction: 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 Direction 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 Reverse direction.
