Error Comparison of Different Acoustic Infinite Element

Abstract:

On the basis of previous studies, various shape function and weight function of infinite element are researched and summarized into eight methods, and then various infinite element methods can be summarized as general equation, the condition number of various infinite element methods is researched to judge the merits of infinite method. Surface error of selected methods versus frequency and the node number are calculated in this paper. Finally, relatively optimal infinite element methods are summed up according error comparison, which helps to apply appropriate infinite method to solve boundary-value problems on unbounded domains.
