Abstract (EN): The current study discusses the results of parallelisation of a computer program based on the SIMPLE algorithm and applied to the prediction of the laminar backward-facing step flow. The domain of integration has been split into subdomains, as if the flow were made up of physically distinct domains of integration. The convergence characteristics of the parallel algorithm have been studied as a function of grid size, number of subdomains and flow Reynolds number. The results showed that the difficulties of convergence increase with the complexity of the flow, as the Reynolds number increases and extra recirculation regions appear.
