How to model a HEX with different shell thickness (e.g. in acc. with EN 13445-3 para. 13.5.9)?

Jan, please share with us the datasheet or drawing of the design you are trying to accomplish.

Luke, thanks for quick reply!!! Please find attached the sketch from the code showing a fixed tube heat exchanger shell with different thickness.

There is a split shell command to be able to split the shell into as many sections as you need. This is helpful for including the amount of welds required to fabricate the vessel and to design vessels like you have here. With each shell section you can have varying thicknesses.

Thanks again for quick reply! I'm aware of this function and have figured out the problem. My hex is NEN-type. It seems the function is not working on N-type hex. Unfortunately I could not upload the file for example.

Please submit a service request with the file attached and screenshots of what you believe to be the issue and we can investigate fully.
