Hello everyone! I am trying to model the flow of air through a window that is between two zones. When I try to run the simulation I am resisted by the following error * Severe * GetAirflowNetworkInput: No External Nodes found in AirflowNetwork: Multizone: ExternalNode. There must be at least 1 external node defined. * Fatal * GetAirflowNetworkInput: Errors found getting inputs. Previous error (s) cause program termination.
But in the AirflowNetwork: SimulationControl section, in the field:Wind Pressure Coefficient Type I selected SurfaceAverageCalculation. From the file InputOutputReference pages 1042-1043 it reads "With this choice you do not have to enter any of the following objects: AirflowNetwork: MultiZone: Wind Pressure Coefficient Array, AirflowNetwork: MultiZone: ExternalNode and AirflowNetwork: MultiZone: WindPressureCoefficientValues. " So I can't understand what the problem is.
I tried to add an External Node, obviously without using it in the model as I don't need it, but it keeps giving me this error.
Has anyone ever had this problem? Could you help me solve it? Thanks in advance
