I am an user in Australia. Unfortunately my computer at work cannot write Chinese. Who use flair to simulate air conditioning system(air quality issue) and fire spread? Sometimes the results didn't make sense. The manuals are somehow useless. It is very frustrated. Hope I can make friends here and exchange information about using Phoenics. Thanks
I use core model to simulate air flow in buildings.It gives satisfactory results.Maybe you can try this model.
For air quality simulation, Airpak(Fluent) is an alternative.
