A dual-level method of fundamental solutions for three-dimensional exterior high frequency acoustic problems

Li, Junpu; Qin, Qinghua; Fu, Zhuojia


Physical essence of the fictitious boundary of the method of fundamental solutions has been a mystery for a long time. In this study, we attempt to explain the reason why fictitious boundary has such a dramatic effect on numerical results. The influence law of the fictitious boundary on numerical results is revealed. Based on this understanding, a dual-level method of fundamental solutions with self-adaptive adjustment coefficients is proposed. The competitive attributes of the method are that...[Show more]
