A novel approach to the development of inΓΏnite element formulations for exterior problems of time-harmonic acoustics is presented. This approach is based on a functional which provides a general framework for domainbased computation of exterior problems. Special cases include non-re ecting boundary

β¦ Synopsis
We describe an approach to solve numerically external scattering problems for the Helmholtz equation. The approach is based on the difference potentials method with the use of a special form of the potentials satisfying the radiation condition.

A new domain decomposition method is presented for the exterior Helmholtz problem. The nonlocal Dirichlet-to-Neumann (DtN) map is used as a nonreflecting condition on the outer computational boundary. The computational domain is divided into nonoverlapping subdomains with Sommerfeld-type conditions
