We consider progressive waves such that the time independent potential satisΓΏes the Helmholtz equation, for example, the travelling wave di racted from a body. In order to model the wave potential using ΓΏnite elements it is usual to discretize the domain such that there are about ten nodal points pe
A novel family of infinite wave envelope elements is described which can be used in conjunction with conventional finite elements to model the transient wave equation in unbounded regions. The elements are obtained by applying an inverse Fourier transformation to a mapped wave envelope formulation i
