Abstract
We consider a new approach to modeling wave propagation in urban environments, based on the Transmission Line Matrix (TLM) method. Two-dimensional simulations are performed using a map of a city A renormalization technique is proposed to convert the results to the three-dimensional space. Our approach provides good predictions for the intensity of a wave when compared with in-situ measurements and is appropriate to very fast massively parallel computations. In order to provide a performance analysis, the algorithm has been used as a benchmark on different parallel architecture (CM200, CM5, IBM SP2 and Cray T3D).
