In contrast to the Finite Element Method (FEM), the application of the BEM requires the discretization of the boundary of the structure only, but not the whole volume of the halfspace. Thereby, compared to the FEM, the number of discrete elements is reduced so that complex structures can be modeled.
BEM – Boundary element method
Presently, in many cases, the Boundary Element Method is applied as sophisticated numerical tool to calculate the sound radiation and the sound propagation into the infinite half space.
