Maximum Displacement Constraint

With the advanced user settings it is possible to define a limit for the displacement (translation or rotation) for any applied force.

Because for every force a connector (default RBE3) is created the maximum displacement constraint can be set for this connector.

To apply a maximum displacement constraint in one direction the following commands can be used:

In the above case, the connector of Force_1 is given an additional displacement constraint of 0.001m in Event_1. The direction of the displacement is defined by the three "Axis" entries as a vector. To activate the constraint for several events, copy the first line and change it to the name of the other load cases. Make sure you enter the correct force name for the connector you want to constrain.

Add also the following line if it is meant as a rotation constraint:

Below an example of a beam on which a force of 1000 N in z direction is applied, with and without a maximum displacement of 0.001 m.
