With the advanced user settings it is possible to define a limit for the displacement (translation or rotation) of any surface or non-design on which a boundary condition has been applied. The settings required for this are listed below:
event.Event_1.condition.maxDisplacement1=1 |
Add the also the following line if it is meant as a rotation constraint:
boundaryCondition.maxDisplacement1.maxDisplacement.rotation=true |
In the above case, the surface on which Force_1 was applied 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, if the constraint is to be direction independent, these lines must be deleted. 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 surface you want to constrain.
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.
