It took me a some hours of fiddling around but I did manage to get it to run. I’m not completely sure it had anything to do with the Refrigerant. It has again stopped running as I continue to edit and the message I get now is “12 Bad Building Components” which is an absolute show-stopper -- eQuest provides no explanation. When I did get the model to run, I would get a boatload of “MechEquip_Sim convergence failure” cautions, again unexplained. Needless to say, the refrigeration version of eQuest is challenging. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I started out building off the Grocery model, simplified the refrigeration entries, and found I had to edit the INP file in a text editor -- the interface seems to cause lots of problems.

Very useful.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m continuing to work on it. Hopefully I can get it running again.
