Abstract：When the finite element and boundary element are used to simulate the effect of muffler , commercial simulation soft-ware SYSNOISE and ANSYS commonly used run on a single computer ( namely not directly run on the parallel machines ) , some-times an accurate solution can ’ t be obtained for days or even 20 days because of a large amount of numerical simulation.A paral-lel machine with high-performance , which is built from 32 commercial computer , is used for the numerical simulation of the muffler effect.At the same time, the finite element and boundary element simulation software are transformed into programs which can run in the MPI ( message passing in interface ) parallel environment in order to reduce the cost; numerical simulation.The data is reliable through data simulation experiment , the computing speed of the parallel computer with high -performance is 25~30 times of the single computer , which shows that numerical simulation results of the parallel machine with high performance on noise-elimination is feasible.
