This paper describes the reconstruction of the old CAE system which has already been constructed to design an optimal high-intensity ultrasonic system. As the old CAE system employs the optimizing program based on the simultaneous search plan, the system takes a long time to search the optimal solution of the complex ultrasonic system with many design parameters. In this paper, the search algorithm which can search the optimal solution of the complex system in a short time is proposed, and the algorithm is named the improved local search method ( ILSM ) after the local search method. In addition, the new CAE system is reconstructed by the use of the optimizing program based on the ILSM. Then, the two-dimensional and three-dimensional designs of a solid horn that is one in several components of the high-intensity ultrasonic system are presented for the examples of applications of the new CAE system. As a result it is confirmed that the concept and the formulation of the ILSM are quite right, and that the new CAE system can efficiently search the globally optimal solution.
