New Accurate 3-D Finite Element Technology for Solving Geometrically Complex Coupled-Field Problems

A novel 3-D transducer formulation has been developed to solve geometrically complex coupled-field problems. The transducer is compatible with both structural and electrostatic solid elements, which allows for modeling complex devices. Through internal morphing capabilities and exact element integration the 3-D transducer element is one of the most powerful coupled field FE analysis tools available. To verify the accuracy and effectiveness of 3-D transducer a series of benchmark analyses were conducted
