This paper is concerned with the parallel implementation of the boundary element method and its application to the exterior acoustical scattering problem. The numerical implementation is based on a Galerkin-type formulation of a Burton-Miller equation proposed in references [1,2]. This scheme can avoid sensitive properties of hypersingular integration, simplify the numerical implementation, and improve the quality of the numerical solutions, especially in the range of high frequencies. An a posteriori error estimate proposed in reference [1] is implemented. In essence, a complete parallel implementation of the boundary element method, including the parallel formation of the linear system, a parallel dense solver, and a parallel algorithm for postprocessing (error estimation), are presented in this paper.

In this paper the application of the two-dimensional boundary element method to the scattering of plane sound waves from an infinite cylinder in a fluid is presented. The acoustic equation of the wave motion in a barotropic, inviscid fluid is deduced from the linearized hydrodynamics equations and t
The interaction of acoustic waves with submerged structures remains one of the most di cult and challenging problems in underwater acoustics. Many techniques such as coupled Boundary Element (BE)=Finite Element (FE) or coupled InΓΏnite Element (IE)=Finite Element approximations have evolved. In the p
