Smartfire: An Integrated Computational Fluid Dynamics Code And Expert System For Fire Field Modelling

Taylor, S., Galea, E.R., Patel, M.K., Petridis, M., Knight, B. and Ewer, J., 1997. Smartfire: An Integrated Computational Fluid Dynamics Code And Expert System For Fire Field Modelling. Fire Safety Science 5: 1285-1296. doi:10.3801/IAFSS.FSS.5-1285


ABSTRACT

SMARTFIRE, an open architecture integrated CFD code and knowledge based system attempts to make fire field modeling accessible to non-experts in Computational Fluid Dynamics (CFD) such as fire fighters, architects and fire safety engineers. This is achieved by embedding expert knowledge into CFD software. This enables the 'black-art' associated with the CFD analysis such as selection of solvers, relaxation parameters, convergence criteria, time steps, grid and boundary condition specification to be guided by expert advice from the software. The user is however given the option of overriding these decisions, thus retaining ultimate control. SMARTFIRE also makes use of recent developments in CFD technology such as unstructured meshes and group solvers in order to make the CFD analysis more efficient. This paper describes the incorporation within SMARTFIRE of the expert fire modeling knowledge required for automatic problem setup and mesh generation as well as the concept and use of group solvers for automatic and manual dynamic control of the CFD code.
