摘要
In an improvement over conventional finite element techniques, an oblate spheroidal infinite element is used for the modeling of acoustic fields in exterior, fluid-filled domains surrounding a structure This oblate infinite element is based on a multipole expansion that describes, to arbitrary accuracy, any scattered and/or radiated field exterior to an oblate spheroid of any eccentricity. The oblate infinite elment is readily incorporated in any structural or acoustical finite element code.
