I want know, how the connecting 2D & 3D elements by Hex/Penta elements & when to use of Rigid elements (RBE)? Where the use of types of RBE?
One screenshot for better understanding your question?
Or refer some topics first
Hi Frnds,
i need to know what is difference between RBE2 and RBE3 element. Anybody please give answer.

RBE2 == Stiff
RBE3 != Stiff
So different

thank u for your ans. but don't get clearly. can you explain in detail plzz.

Any proper viedo or tutorial ?
Hi,
In simple terms RBE2 adds stiffness to the body and thereby it will not deform, that is the body will be rigid whereas for RBE3 the body will be deformable.
Please go through https://connect.altair.com/CP/SA/training/self_paced/aero_v13/PDF/chapter7_demonstration.pdf which is an example covering the basics behind the creation and visualization of 1D elements, ranging from simple rigid entities to more complex 1D elements.
For more please go through Practical Aspects of Finite Element Simulation (A Study Guide) ebook where these concepts are covered.
