How to quickly solve a large body?

      Hi all.

      Can you please tell me the fastest way to solve the problem? I have two pipes of different diameters one inside the other. The outer pipe is a rigid body. Pipe length 10 meters. I need to put pressure on the inner tube and see how it deforms, look at the stress in the bends.

      I can do it in 3 ways: solids, shells, beams. Solids and shells for a very long time, because there is a lot of mesh. How can you quickly solve this problem? Beams will be able to show what I need?

      Hi,

       

      You can use shell bodies. Assign rigid behavior to the outer pipe. Define contact between both the pipes. Use a coarse mesh to sove the model and then refine as needed.
