非稳定有限分析格式

On Unsteady Finite Analytic Format

八十年代初,由Iowa大学陈景仁提出的有限分析法作为一种数值计算方法有独特的优点,它逐渐的为国内外从事数值计算的同行认识和接受,本文除简单介绍其基本原理和思路,主要推演了一个新的非稳定有限分析格式。与解析解的计算结果比较,相当接近,可推广试用。

The finite analytic method(FAM) brought forward by prof. Chen Jingren of Iowa University in tbe early 1980's has unique advantages as a numerical method which is recognized and accepted gradually by professionals in the field of numerical computation at home and abroad. Apart from a brief introduction of the basic principle of FAM a new format for unsteady finite analysis is mainly derived in this paper. Compared with the results calculated by analytical solution, both are quite close. So this format can be popularized for use.
