- What Is The Difference Between A Kinematic (RBE2) And A Distributing . . .
So, let us first start by understanding the key difference between kinematic couplings (RBE2) and distributed couplings (RBE3): RBE2 elements add infinite stiffness to the nodes being constrained; RBE3 elements provide a distributed connection, which does not influence the local (or global) stiffness of the model

What is the difference between RBE2 and RBE3 elements? Both elements "look" the same, in that they have a single node connected to one or (usually) multiple other nodes The difference is that the RBE2 element adds (infinite) stiffness to the structure, while RBE3 elements "distribute forces" around the connected nodes, without adding

stiffening effect on the structure, not only between the independent node and the dependent ones, but also between a dependent node and another dependent node On the other hand, the RBE1 behaves like a RBE2; the only difference is that on the RBE1 the independent degrees of freedom can be distributed between different nodes In this
- RBE2 VS RBE3 - FEA for All
RBE2 and RBE3 are basically rigid elements that are use to connect mesh sets together The name is similar, but there is a fundamental difference between them: RBE2 transmits the displacements and RBE3 transmits the Loads (MPC Forces)

The RBE2 impose stiffness and are often called "infinitely stiff", while the RBE3 is an interpolation element and does not impart additional stiffness to the model To help illustrate this difference between the RBE2 and the RBE3 consider the following simple shelf model

Unlike the RBAR and RBE2 elements, the RBE3 doesn’t add additional stiffness to your structure Forces and moments applied to reference points are distributed to a set of independent degrees of freedom based on the RBE3 geometry and local weight factors To learn more about rbe2 vs rbe3 you can visit my blog in the following address:

RBE2’s fix displacements rotations between the nodes, RBE3’s distribute forces So an RBE2 will introduce extra (sometimes fake) stiffness into your model while an RBE3 is meant to take the force from one node and beam it out to more without adding stiffness

In general you should use RBE2 for constraints and RBE3 for loads *RBE2 creates a "rigid motion" whereas RBE3 creates a "load distribution" Please find below a brief summary of each: Any way to get the RBE3 to distribute the load equally instead of weighting the distribution by distance?
