An error occurred while calculating the fixed tube sheet for a floating-head heat exchanger, with the message stating that the nominal diameter is invalid. I’ve also checked the data, but I didn’t find any issues. Has anyone else encountered this problem? How did everyone solve it? Which data was incorrect?

It’s version 5.0. Which nominal diameter is referred to in the error message?

Was the nominal diameter specified outside entered incorrectly? It should be Di+80.

Was the nominal diameter specified outside entered incorrectly? It should be Di+100.
