| Abstract: |
| The key techniques for simulating acoustic scattering by the pFFT boundary element method are studied.Burton-Miller formulation is employed to avoid the nonuniqueness problem appearing in the exterior acoustic problems.Hence,the calculation of hypersingular integrals in this equation is studied as constant elements are applied.A plane acoustic wave scattered by a rigid sphere is modelled to validate the developed pFFT boundary element method. |
