瞬态有自由面渗流分析的不动网格──高斯点有限元法

Finite element method of invariable mesh -Gauss point for transient seepage problem with free surface

对于瞬态有自由面渗流问题，建立了一种简单、实用的不动网格─—高斯点有限 元法。该法与变网格法及已有的不动网格法相比，计算量小、格式简单。算例表明了 该法的有效性。

A simplified and practical 'Invariable mesh─Gauss point' finite element method for transient free surface seepage problem is proposed. As compared with other methods such as variable mesh or previous invariable mesh, simple formulation and higher computational efficiency can be obtained. Two examples are given to indicate its efficiency.
