Hello, I am having trouble running my model. It seems to work fine when I enable ideal air loads, however when I try to run with the built HVAC system the simulation fails. There are three PTAC, one split system, and three cooling coils fed from a plant loop utilizing district heating and cooling.
Here is some of the err file
