利用交替方向隐格式研究了一类三维变系数椭圆方程的边值问题,给出了交替方向法的推导过程,建立了相应的误差分析,并进行了数值模拟,结果表明,该格式具有易于计算、求解精确度高等优点.
Three-dimension elliptic equations of boundary value problem, with varable coefficients, is studied by use of alternating direction implicit (ADI) sheme in this paper. The derivation process of the alternating direction method is given. The corresponding error analysis is established. And a numerical simulation is carried out, results of nu- merical simulation show clearly the advantages of simple computation, high precision and etc.
