UTFRG researchers utilize in-house simulation capabilities as a complimentary tool to support experimental testing. The lab has several fire-specific software codes for combustion and fire simulations, including, Fire Dynamics Simulator (FDS), Consolidated Model for Fire and Smoke Transport (CFAST), and Unsteady Ignition and Combustion with Reactions (UnICoRn). The latest versions of other open-source software packages including OpenFOAM for Computational Fluid Dynamics (CFD) and FEniCS for Finite Element Analysis (FEA) are available for research use. Many of these codes are run on our in-house development cluster and on the Texas Advanced Computing Center (TACC) high performance computers.
