wildFireFoam is an extension of fireFoam, an OpenFOAM solver for “…fires and turbulent diffusion flames with reacting particle clouds, surface film and pyrolysis modelling.” It retains all functionality originally included in fireFoam for efficient simulation of complex fire phenomena. Similar to diffusionFireFoam, it also incorporates adaptive mesh refinement (AMR) to increase simualtion efficiency without sacrificing accuracy by updating the computational mesh at runtime and adding resolution only in regions of interest (e.g. where reactions are occuring). It has been designed specifically to reduce computational cost of fire spread and suppression simulations for use in outer-loop processes (e.g. optimization and uncertainty quantification).
