The Walkthru model
contains detailed material information about the building area and is a good
feeder system to the CFAST model.Where CFAST contains the chemistry, burn properties, and ignition
times, Walkthru provides the detailed geometric and material specifications
that architects would need to evaluate strength of building supports and the
like.
The most important
piece of information that Walthru provides to CFAST is the geometry of
objects contained in a room. This information is fed into CFAST to provide
obstacles to the flow of the fire.
The role of Walkthru
is as the visualizer for the fire in progress.It is designed to show the progress of the
fire and smoke and give a visual representation of what can and cannot be
seen.Pictures of how Walkthru views
appear can be found at:
