Two-Model Monte Carlo Simulation of Fire Scenarios

In the probabilistic approach to fire safety design, the answer of the numerical simulation is not any single number, but a probability, at which certain criteria are met. In practice, the best way to perform probabilistic simulation is Monte Carlo, where the simulation is repeated many times with inputs randomly picked from the distributions. In the presentation, a new technique is presented wich accelerates Monte Carlo simulation by combining the results of two different models. The physical and numerical features of the state-of-the-art fluid dynamics fire model are also presented. The model is based on the fast numerical solution of Navier-Stokes equations on rectilinear grids.
