Hi all,
I have two questions about a tubesheet I want to model. See the image I uploaded for an explanation of the situation. The tubesheet is used as a (blind)flange too and has an extra head that is screwed onto the tubesheet.
The image represents a tubesheet with U-bend tubes, but I have a same sort of construction with an heat exchanger with one fixed and one floating tubesheet which both have the same kind of head opposite to the tubes screwed on the tubesheet.

My first question is how I can model such a configuration in PV-Elite? For the stationary tubesheet it looks like configuration e. For a floating tubesheet there is not such a configuration in ASME section UHX. Is this even possible?

For the configuration e I've uploaded two PVI files. One with one flange and one with two flanges. I'm having trouble getting the channel on it correctly. How should I model it?

Thanks in advance for your replies.
