Simulation of Complex Geometry in FDS

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.
