基于面元法的鱼类表面压力以及速度的统计，工程中用高斯列元法进行方程组的求解，结果的显示是使用opencv来实现-hello world!!!

介绍了当今最流行的面向对象的程序设计方法，讨论了这种方法应用在面元法计算中的优点，并详细介绍了该如何用图形用户界面去开发面向对象的面元法程序。(It introduces the object-oriented method which is most popular by now, and discusses the advantage of this method using in the panel method and how

面元法求解面体表面压力分布，速度分布，输出数据文件，便于生成曲线图(The surface pressure distribution, velocity distribution and output data file are solved by the surface element method, which is convenient to generate graphs)
