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

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
boundaryCondition.ModelLoadEvent_Force_1_Force.displacement.x=0
boundaryCondition.ModelLoadEvent_Force_1_Force.displacement.y=0
boundaryCondition.ModelLoadEvent_Force_1_Force.displacement.z=0
boundaryCondition.ModelLoadEvent_Force_1_Force.displacement.ry=0
boundaryCondition.ModelLoadEvent_Force_1_Force.displacement.rz=0

Force_1 has to be replaced with the name of the change desired load to a displacement constraint.
