Develop an efficient, conservative numerical scheme for complex geometry within FDS.

This presentation covers the following topics:
Modeling fire dynamics for Complex Geometry.
Treatment of FDS physics units.
Defining geometries in FDS. Restrictions on GEOM input.
The CATF input namelist.
Workflow showcase through validation case.

Summary:
An add-on to FDS, but requires rewriting on most code units.
Allows imposing triangulated boundary surfaces on the fluid grid.
Ongoing validation and verification.
Ongoing implementation of radiation, mass/heat flux BCs, LES wall models, and others.
GEOMs (in Beta) will be released in FDS 7.
