I have a shell and tube heat exchanger with steam in the shell and water in the tubes, but every time I run a time dependent study, it reads "Solver abnormally terminated; contact support service" after the first iteration. If I don't run the time dependent study, the simulation works; I do need a time dependent study.
Further, I don't understand why my steam is not cooling down, even the slightest bit, but for some reason the water in the tubes is boiling before it gets to its outlet.
I attached the zip file with all my parts and lids for better help.
For starters, turn off nested iterations in your Calculation Control Options. It will take longer, but it won't blow up.
