人工边界方法 英文版
作者:韩厚德,巫孝南 著
出版时间:2012年版
内容简介
  人工边界方法是求解无界区域上偏微分方程(组)数值解的一个重要和有效的方法。人工边界方法的核心问题是在人工边界上如何对已知的问题找出问题的解满足的准确(或者高精度近似)的边界条件。借助于人工边界方法,我们可将无界区域上的问题简化为有界区域上的问题进行数值计算。《Artificial Boundary Method(人工边界方法)(精)(英文)》系统地介绍了人工边界方法的计算格式及其理论基础。《Artificial Boundary Method(人工边界方法)(精)(英文)》可以作为科学与工程计算专业研究生课程的教材,亦可以作为科学与工程计算专业科学技术人员的参考书。
