The Optimization of the Distribution of Source Points for the Fast Multipole Method of Fundamental Solutions Based on Genetic Algorithms
2016
Journal of Mechanical Engineering
Abstract:The computational precision of fast multipole method of fundamental solutions mainly depends on the number and distribution of source points. In order to overcome the difficulty of determining the distribution of source points, GA-based FMMFS is proposed. The theoretical formula of this method is given, and it is used to predict the acoustic radiation field of engine surface. The results show that with the optimized distribution of source points, the number of source points and
