摘要
提要本文通过求解拉普拉斯方程的反变换方程,然后,使用代数法调整网格的疏密,把二维任意边界转换成计算区域为矩形的边界。该方法在调整网格疏密方面比THOMPSON方法简便。用该方法编制的通用程序DAOB,可处理计算水力学中出现的二维任意边界问题。
The two dimensional arbitrarily—Shaped boundaries are transformed onto a rectangular computational field by sdving the adverse—transformation of Laplace's equation and adjusting the spacing and density of the mesh-lines with algebraic method .This method is more uncomplicated than Thompson's in the adjusting mesh-lines. The general Code DAOB on the basis of author's method can be used to treat two dimcnsional arbitrary boundaries in computational hydraulies.
