A finite element method is presented for solving three-dimensional radiation problems in time-harmonic acoustics. This is done by introducing a so-called ''Dirichlet-to-Neumann'' boundary condition on the outer boundary of the domain discretized with finite elements. This DtN boundary condition is a

An exact expression is derived for the finite-part integral #,r-'fdS over a triangular domain S . where r denotes the distance of the points of the triangle from one of its vertices and f is a linear function of the Cartesian co-ordinates. The more general case where r denotes the distance of the po
