This thesis has for goal to define and develop solutions in order to achieve physical simulations on large simulation domains such as industrial sites (Dunkerque LNG Terminal). The simulation model is based on the lattice Boltzmann method (LBM) and allows to treat several simulation cases. The use of several computing architectures are studied in this work. The use of a multicore central processing unit (CPU) and also several graphics processing units (GPUS) is considered. An efficient parllelization of the simulation model is obtained by the use of several GPUS able to calculate in parallel. A progressive mesh algorithm is also defined in order to automatically mesh the simulation domain according to fluids propagation. Its integration on ...
