If your failure criterion is yield, then your structure fails and there is no need to re-distribute the loads.
I guess you have to clarify what is really your failure criteria.

a rigid element stay rigid in linear analysis, dosn't matter if its 2D or 3D.

"The displacement of the slave node is not equal to the displacement of the master".
The displacements are not necessarily equal.
check your model by replacing the rigid element with a pyramid...
I have used both Patran (up to now) and Femap ( till couple of years ago). Patran is more powerfull but not friendly, and Femap is friendlier, and easy to learn and run.
In my opinion, unless you need a feature which is unique to Patran , Femap is a better choice.
