RBE2, RBE3 vs, CP, CERIG,etc in ANSYS

RBE2, RBE3 vs, CP, CERIG,etc in ANSYS

(OP)
I need you!! I've created a model in Patran and a client wants to access to it via ANSYS. The model has MPC (multi-point constraints) defined. In this case, RBE2 and RBE3. The RBE2's are rigid elements that connects a master node (independent) to slaves nodes (dependents) and RBE3's, however, are elements of interpolation, which are used to distribute a load (or mass) of a point to others.

I'm preparing an input file and would like to know what would be the equivalent element in ANSYS to these types of joints. CP, CERIG,...? Can you tell me what is most appropriate for RBE2 and RBE3? Or if there is another element that I'm not considering...

I hope you can help me! I just know the basic of ANSYS!

Thanks a lot!!!! And have a really nice weekend!!
