Recently I am doing Natural Cross Ventilation Simulation.I input:Room Air Model Type= cross ventilationRoom Air Setting=Cross Ventilation (Recirculation)Zone Air flow > Zone Ventilation Design Flow Rate.but the following errors ...****Program Version,EnergyPlus-Windows-64 8.1.0.009, YMD=2016.03.02 21:10,IDD_Version 8.1.0.009
** Severe ** Problem with RoomAirSettings:CrossVentilation = Z-1
** ~~~ ** AirflowNetwork airflow model must be active in this zone
** Fatal ** GetAirModelData: Errors found getting air model input. Program terminates.
...Summary of Errors that led to program termination:
..... Reference severe error count=1
..... Last severe error=Problem with RoomAirSettings:CrossVentilation = Z-1Please help to inform the proper steps.
