Hi
I have a pipe support that in on the vessel.

Is there any way that I can include it in the fesus model or may be model the vessel expasnion in any way?



Best regards

Hi again
Can I use "Inner friction" or "coupling" between two pipes?

BEst regards

Hi Ali,

This specific component is not possible to model. You can create an alternative model using the rectangular duct but this is for quite advanced users and not officially recommended because the results must be examined in detail according to the different loadcases. It is not just modelling clicking result and checking for too high stress utilization.

Like you already mentioned you can make use of ROHR2 to connect the pipe with the vessel to get the correct displacements due to thermal expansion of the vessel etc. This tutorial should give you an idea:

Hello,

I think, original question was; How can we consider the vessel support displacement on piping ?

Thank you in advance

If you are only interested in the displacement of the attachment point you can either:
- use rigid beam with the correct temperature and material to model the support structure, then use an internal support to connect it to a pipe
- if pressure expansion of the vessel is interesting: use a fesu model with a trunion at the support lug position and attach you pipe with an internal support on this trunion.

Best regards
