Dear All,

I have a constant volume 100% outside air evaporative cooler for a kitchen.
The CFM is 4500. So I set the design flow rate 4500 and outside air flow
4500. When I performed simulation, the simulation was terminated due to
errors. However, there is no error shown in the list of errors. In
addition, if I increase the design flow rate above the outside air flow
rate 4500, then this problem will be gone.
Did anyone have this problem before? How could I fix it?
Thank you!
