Loads
RBE2 & RBE3 discrete ties can be used by modifying already generated remote loads.
By default all remote loads are distributed with a RBE3 element. To change a remote load to a load distributed by distribution with a RBE2 or RBE3 element the following commands command can be added to the Advanced User Settings:
boundaryConditionconnector.ModelLoadEvent_Force_1_Force.tyingModetype=RBE2boundaryCondition.ModelLoadEvent_Force_2_Force.tyingMode=RBE3 |

Force_1 & Force_2 have has to be replaced with the names name of the change desired loadsload. |
Displacement Constraints / Rotational degrees of freedom
...
Therefore, a dummy remote load has to be created with a load value. The dummy load can then be modified to a displacement constraint with a RBE2 element with the following commands. Unconstraint directions or rotations are left free to enable rotation. Ideally, the dummy load is applied in a direction of a translational displacement constraint so that the dummy load is without influence.
boundaryConditionconnector.ModelLoadEvent_Force_12_Force.tyingModetype=RBE2 |

The GUI does not support rotational degrees of freedom yet. The optimisation must be executed in the command line. |
| Info |
|---|
Displacement constraints can only be applied with RBE2 elements and not with RBE3 elements. Displacement constraints on RBE3 elements make the FE matrix unsolvable. |
