Loads
RBE2 & RBE3 discrete ties can be used by modifying already generated remote loads.
To change a remote load to a load distributed by a RBE2 or RBE3 element the following commands can be added to the Advanced User Settings:
boundaryCondition.ModelLoadEvent_Force_1_Force.tyingMode=RBE2 boundaryCondition.ModelLoadEvent_Force_2_Force.tyingMode=RBE3 |
| Info |
|---|
Force_1 & Force_2 have to be replaced with the names of the change desired loads. |
Displacement Constraints / Rotational degrees of freedom
Displacement constraints can also be created with RBE2 Elements. Thus, rotational degrees of freedom can be unconstrained.
Therefore, a dummy remote load has to be created with a load value in one direction which will be constrained. The dummy load can then be modified to a displacement constraint with a RBE2 element. E.g. with the following Advanced User Setting commands the rotation around the x-axis is freed:
boundaryCondition.ModelLoadEvent_Force_1_Force.tyingMode=RBE2 |
| Info |
|---|
Force_1 hasto be replaced with the name of the change desired load to a displacement constraint. |
