This paper describes a family of axisymmetric, spheroidal 'wave envelope' elements for modelling exterior wave problems. They are of variable radial order and can be used to represent steady and transient wave fields. The formulation is presented for the axisymmetric case using elements which are ba

Variable order mapped in"nite wave envelope elements are developed for "nite-element modelling (FEM) of acoustic radiation in a uniformly moving medium. These elements can be used as a non-re#ecting boundary condition for computations on an in"nite domain in which a radiating body is immersed in a m
The infinite element method is employed to approximate the solutions of Webster's horn equation and Berkhoffs equation for water wave radiation and scattering in an unbounded domain. Functionals based on the first variational principle are presented. Two new infinite elements, which exactly satisfy
