Update: To debug, I switched a pair of Heater/Coolers for the Heat Exchanger and was able to solve the Flowsheet. Then I swapped the Heat Exchanger in and the Flowsheet solved. I must have configured the Heat Exchanger in error. I thought that the numbers looked strange even accounting for partial vaporization. Do you see anything to report?
COFE v3.2.0.22
The Inlet 2 and Outlet 2 vapor fractions differ in the Heat Exchanger Unit. Is this correct?
I am sending an fsd for your review.
