Hello Dave,

Thank you for your reply.

So, as per your response I should not use UDL to make up the difference in
the weight of the heat exchanger. If not so then how can I ensure that the
heat exchanger modeled on CAESAR-II shall have the same weight as that given by the manufacturer. Which of the following approach is more correct / viable:-

1.) Play around with the fluid or materiel density to match up the operating weight of the heat exchanger.
2.) Play around with the thickness of the elements used to model the
heat exchanger

Awaiting your expert advice.

Thank you in advance.
