Loads
By default all remote loads are distributed with a RBE3 element. To change a remote load to a load distribution with a RBE2 element the following command can be added to the Advanced User Settings:
connector.ModelLoadEvent_Force_1_Force.type=RBE2 |
Force_1 has to be replaced with the name of the change desired load.
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. 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.
connector.ModelLoadEvent_Force_2_Force.type=RBE2 |
Force_2 has to be replaced with the name of the change desired load to a displacement constraint.
Limitations:
The GUI does not support rotational degrees of freedom yet. The optimisation must be executed in the command line.
Displacement constraints can only be applied with RBE2 elements and not with RBE3 elements. Displacement constraints on RBE3 elements make the FE matrix unsolvable.
Several RBE2 elements on the same application region in the same Event make the FE matrix unsolvable.
