通过将物体划分为有限单元，并满足单元间流动的连续性和压力平衡，将流体在多孔介质中的流动视为达西定律的推广情况。将这一技术应用于存在自由面的流动问题，发展了一种描述自由面的系统变分方法。材料的渗透率可以用一个各向同性、空间变化的二阶张量来描述。这类解仅限于二维问题，并给出了平面条件和轴对称的例子。
The flow of liquids through porous media is treated as a generalized case of Darcy's Law by dividing the body into finite elements and satisfying continuity of flow and pressure equilibrium from element to element. This technique is applied to flow problems where a free-surface exists and a systematic variational method for describing this surface is developed. The material permeability may be described by a non-isotropic, space varying, second rank tensor. The class of solutions is restricted to two dimensional problems and examples for plane conditions and axial symmetry are given.
