Abstract :
This paper develops the fast multipole method (FMM) accelerated the boundary element method (BEM) for large-scale underwater acoustic problems. The Burton-Miller formulation is employed to overcome non-uniqueness difficulties in the conventional BEM for exterior acoustic problems. The computational efficiency is further improved by adopting the FMM to solve system matrix equation. Numerical results clearly demonstrate the complete reliability and efficiency of the FMM-BEM algorithm.
