Any opinions, findings and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation (NSF). This material is based upon work supported by the National Science Foundation under Grant No. Some of the theory, applications, verification, and validation of Gpyro, its predecessors, the material property estimation algorithm, and linking to FDS is scattered over several publications listed in the References section below. Gpyro was originally developed at UC Berkeley under NASA sponsorship as part of the Forced Ignition and Spread Test (FIST) project and a Graduate Student Researcher Program (GSRP) extension to FIST and later under NSF Award 0730556, "Tackling CFD Modeling of Flame Spread on Practical Solid Combustibles".

The developer is in the process of preparing updated documentation, but this is a side project that only gets worked on in his spare time. DocumentationĪlthough a Users' Guide and Technical Reference have been prepared and are available by SVN checkout, these documents are woefully out of sync with the current code in the repository. To download the latest version of Gpyro, after installing Subversion, type: svn checkout svn:///gpyroĪ SVN user interface such as SmartSVN can also be used to access the code repository. At the present time, brute force search, genetic algorithm optimization, genetic algorithm/simulated annealing, stochastic hillclimber, and shuffled complex evolution optimization methods are available. Coupled to Gpyro is a material property estimation program that can be used to help estimate the required material properties from experimental data (Cone Calorimeter or similar, thermogravimetric analysis, and differential scanning calorimetry). It can be applied as a boundary condition in a modified version of FDS6 (disclaimer: Gpyro and its linking to FDS is in no way supported by or developed by NIST or VTT). Gpyro contains the physics necessary to simulate pyrolysis of thermoplastic and charring solids, intumescent coatings, and smolder in porous media. Gpyro can be used for 0D, 1D, 2D, and 3D simulations and can write NIST Smokeview files for visualization of 2D simulations. Gpyro is an open source computer model that describes the thermal response of solid materials exposed to radiative or convective heating, including thermo-oxidative pyrolysis of the condensed phase.
