I increased the iteration count to 500 but still the simulation fails after 11th iteration saying the same message that it can’t find find located at “C:\Users\yjaechung\butterfly\simple_hvac2\log\buoyantBoussinesqSimpleFoam.err’ can’t find file.:”
I am using the same definition you provided without changing any inlet or outlet values. and I didn’t realize that there is a right or wrong value for outlet. I just left it at default value. I am quite puzzled and think maybe its an issue with my computer.
