The FEMLAB&reg software package was used to develop and solve acoustic scattering models from fluid, rigid, and elastic spheres immersed in a fluid medium, for which analytical solutions are available. The entire computation domain is modeled as a sphere filled with fluid domains. It is found that the FEM provided accurate predictions of wave scattering by three types of scatterers, fluid, rigid immovable, and elastic. ER -
