This paper describes the implementation of a fire field model in the parallel computing environment offered by multiple transputers. The fire model is built into the general purpose SIMPLE‐based CFD code HARWELL‐FLOW3D. The technique of domain decomposition has been applied tb convert the conventional serial version of FLOW3D into a code capable of efficiently utilizing an arbitrary number of transputers. Fire simulations consisting of up to 24 000 computational cells are performed on parallel systems with up to 15‐processors. The run time for this simulation has been reduced from over 4 days on a single processor to just over 8 h on the 15‐processor system. An interactive graphics system has also been developed which runs in parallel with the main computations.
