Boundary element method for the solution of Helmholtz integral equation
Moses, Pavel
We apply boundary element method for the solution of Helmholtz integral equation, and we compute values of pressure, or its derivatives on the boundary. Solution at an arbitrary point near the barrier can be computed simply by substituting into the formula. Our method is demonstrated on an example of computeation of pressure field near a barrier of the type of unit circle for the case of excitation by a plane wave.

Metoda hraničních prvků pro Helmholtzovy rovnice
Moses, Pavel
The paper shows application of BEM for solution of time-harmonic scattering problems modelled by Helmholtz equation in two dimensions. It deals with computational issues of collocation and Galerkin variants of BEM, such as integration of strongly-singular kernels which arise from boundary integral reformulation of the problem.
