[EnergyPlus_Support] Re: AFN How to Simulate Hung-Windows?

["tobiasschulzeoooitu" <tobias.schulze@xxxxxxxxxxxxxx>]

Dear Lixing,

it does, if you chose a "detailed opening" for the bidirectional flow and as a second pseudo opening a very small crack on some other construction than the window (only to have two openings - which is necessary). I checked it against some simple analytical solutions and it worked out fine.

Any ideas for hung-windows and cross-ventilation?
