Subject: Re: [DCHAS-L] Chemical Dispersion Modeling

Guys,

Thanks for the responses thus far. I've ran ALOHA in the past, and I've encountered MARPLOT outputs. One of the concerns though is the 2-day nature of their outputs. Basically they're good for downwind hazard zone and stand off distance calculations in an open field. However they often do not address 25 foot tall concrete barrier walls along highways, or large quarter mile long by 7 story tall buildings. 

Is there any knowledge of a system similar to structural blast consequence software packages, that allows a user to place shell structures inside of a virtual environment and then run the simulation?

I've heard some of these may exist as modules within larger risk modeling softwares. 

Thanks,

Craig
