Where can I find an ATM simulation software to investigate traffic flow capacities? Does anyone know what software is suitable to investigate air traffic flow capacities in various FIR's / routes. I need to see the effect of temporary reserved ares due to military activities, weather, changes of routing due to LOAs. Taking into account meteorological data would be advantage but it is not necessary.

It would be great if it will be possible to emphesize (colours, histogram, ...). usage of FIR areas. 

What kind of software tools are used by EUROCONTROL or ATM consultancy firms providing this service. What standard tools commercially available (or for free)?
I have already found answer for my problem. ACES and FACET from NASA Aviation System Division solve my problem. It should handle all statistical data, it has statistical output as well and it could also handle meteorological data. Currently this SW use FAA and some airline companies to modelate ATM concepts (aviationsystemsdivision.arc.nasa.gov).
Thanks for all your help!
