I have tried to use the NIST for many times, and there is a pdf file attached, where I explained the methods and also the problems. If we could even solve some of those problems and re-import the results to NIST, there is still some things wrong. As I found, NIST solve the problems in LES model, which is not the common and reliable turbulence model for ventilation simulation. As I now the best for such simulations is K-epsilon RNG model.

Why no one try to make it possible exporting to other more common CFD software, such as Fluent?, which is available in many universities and different research units.

It is really hard to accept that there is no public access to Winair, while it seems that this is the only usable CFD software, which can work with CFD. For exporting to energy simulation programs there are many choices while Ecotect has its own ability too, but there are a limited programs for CFD simulation.

Why you did not make Winair available as a web-based program, at least? Then many people could run their different models there, help to improve the program and find the inabilities.
