New Visualization for Fire, Smoke, and More

September 7, 2016
We are currently developing new visualization for many fire and smoke effects that are needed for both fire and evacuation modeling. Much of this is driven by a need to integrate evacuation results with fire and smoke visualization, along with other representations of FDS data.
