Abstract

The infinite wave envelope formulation has been shown to be able to accurately model different types of acoustic radiation problems. The large calculation speed advantage over the boundary element method has been demonstrated. In a wave element solution, normally both conventional finite elements and low order wave elements are used for high accuracy solutions. Moving to higher order elements allows the element to better model the acoustic near field, and in some cases the need for conventional finite elements is eliminated
