Dear All, I wondering how are you model air contact: there is two zones (e.g. two rooms) and they are connected by air (e.g. doorway), there are no mechanical ventilation or intensive, one direction, air flow. I think to assume some massless construction between this zones, but what resistance will be appropriate? Or maybe some both direction air flow, but how can I assume the value of the flow? Do you have some idea? Kind regards, Karol ------------------------------------------------ Karol Bandurski MSc.
