Hello to All,

Can anybody review this model and write opinion. Is it necessary to model vessel like this. I put file in attachment.

The vessel body itself shouldn't be rigid, just use pipe of the appropriate diameter and thickness. Those ficticous horizontal elements don't really exist, so thse do need to be dummy rigid elements.

you have not defined or showed which nozzle your connecting to? do you have nozzle loads avaliable? if not considered as said by richard.

I just want to clarify modeling bracket supports on vertical vessel. When I model vessel I use rigid elements without weight but I put diameter, wall thickness,temp...etc

For nozzles I create rigid element from center of the vessel to starting point of nozzle. Than I create nozzle as pipe with real diameter, sch, and put anchor with c node to the end node of rigid where nozzle starting. I have allowable loads for nozzles and that must be verified. That is clear for me. This is stripper column connected with piping to reboiler. Each vessel has their own structure where is installed, temperature is 200°C and thermal movement for both vessels are big. I just want to be sure about best way how to present support for this vertical vessel. I can put in the middle of column node, put restraints. Is this enough accurate.

In attachment is CAESAR II file of vessel.

Here is zip file of model.
