Verification and Validation Process of a Fire Model



Kevin B. McGrattan, Simo A. Hostikka


Fire simulation tools are used frequently in the fire safety assessment of nuclear and other industrial installations. They are also used in the context of probabilistic fire risk assessment as deterministic models providing the relation between the random conditions and the consequence of an accidental fire. Fire Dynamics Simulator (FDS) is a computational fluid dynamics code developed specifically for the simulation of fire driven flows and heat transfer processes. FDS is currently the most commonly used fire model globally, and a subject of continuous validation studies by the code developers and users. The purpose of this paper is to provide an overview of methodology that is used for the estimation of model uncertainty, and to describe the implementation of the systematic and transparent quality assurance procedures for an open-source computer code.
