Abstract: An advanced numerical calculation scheme based on finite and boundary elements as well as multigrid methods is presented. This scheme is used for the precise forecast of the dynamical behavior of piezoelectric, electrostatic and, magnetomechanical devices, especially sensors and actuators. Application examples include solenoid valves, piezoelectric source for the generation of acoustic shock waves, magnetic surface acoustic wave (SAW) filters, electrodynamic loudspeakers and magnetostrictive tool actuators.
