本文提出了一个改进的局部有限元法以计算三维波浪问题。与K.j.Bai和R.W.Yeung所建立的局部有限元法相比,除了内域的势函数以外,不再有新的未知量,计算机程序的编制也要简单得多。
This paper presents an improved local finite element method to calculate the three-dimensional wave problem. Compared with the local finite element method established by K.j.Bai and R.W.Yeung, there is no longer any new unknowns other than the potential functions of the inner domain, and the compilation of computer programs is much simpler.
