フーリエ級数と有限要素法による2次元浸透流問題の解法

抄録

In order to solve water pollution problems in abandoned mines, one of the authors has tried to analyze the behavior of ground water flowing through the underground in mine area based on the Darcv's flow in homogeneous media. This analysis has carried out on a certain model by using the finite element method. Although the analysis is annlicahlv as limo ac the model is simple, there may be difficult to apply universally since the more the model iscomplex. the vaster the calculation becomes.
This paper deals with the solving method of that problem by using both the finite element method and Fourier series By this method, analysis of the boundary value problems becomes easy and moreover the accuracy of the analvsis is improved and calculating time of a computer can be shortened.
