Hi all,
I have many errors when I run the simulation but I don't understand the problems and I don't know how to resolve them. If someone can help me that can be very useful ! I copy-past the kind of errors I have.
CheckWarmupConvergence: Loads Initialization, Zone="AHU 4" did not converge after 25 warmup days. ...Environment(SizingPeriod)="BALTIMORE BLT WASHNGTN INTL ANN CLG .4% CONDNS WB=>MDB" ..Max Temp Comparison = 0.14 vs Temperature Convergence Tolerance=0.40 - Pass Convergence ..Min Temp Comparison = 3.79E-006 vs Temperature Convergence Tolerance=0.40 - Pass Convergence ..Max Heat Load Comparison = 0.0000 vs Loads Convergence Tolerance=4.00E-002 - Pass Convergence ..Max Cool Load Comparison = 0.5164 vs Loads Convergence Tolerance=4.00E-002 - Fail Convergence
UpdateZoneSizing: Cooling supply air temperature (calculated) within 2C of zone temperature ...check zone thermostat set point and design supply air temperatures ...zone name = AHU 1 ...design sensible cooling load = 812355.99 W ...thermostat set point temp = 0.000 C ...zone temperature = 26.809 C ...supply air temperature = 26.667 C ...temperature difference = -0.14226 C ...calculated volume flow rate = 4319975.64733 m3/s ...calculated mass flow rate = 5173659.00476 kg/s

Thank you very much for your help !
