Boundary condition for slab

Hi every one,

I am trying to model a slab with SOLID65 element. I have confusion about setting boundary condition. SOLID65 have only 3 DOFs: UX, UY, UZ. How should I make a simply supported or fixed for this slab? I tried with SHELL181. It worked well, but SHELL have 6 DOFs.

Please give me some advises. Thanks a lot.

  • Thanks for your answer. But the problem I am facing here is SOLID element don't have ROT DOF, I'm confused about how to model Simply Supported. I tried to lock all DOFs (UX,UY,UZ; and it turned to be a fixed support) and do a verification for the result by natural frequency, it seemed to be OK. But I still don't know how to simulate the simply support.

  • Thank you so much. I will read about it now.
