Hi

Would you please help me with this case

I have an assembly in that parts are both in contact with each other and also connected with bolt. My question is if I define only EBE2 to connect parts, where bolts are located, do I have to define contact between parts which are touching each other too?? or it is not required to define contact between them and RBE2 connection is enough.

 

Thanks for your help in advance

    you can try with Rbe2 and if results are not as expected then go for contact.Load & Boundary condition direction is also important for such cases.

    Your mesh is not so 'good' enough to give you reliable results. Please refine firstly.
