论文摘要
最近，非线性持续方法已用于为稳态Richards方程解决数值解决边界值问题。该方法可以被视为具有最简单形式的预测 - 校正过程，该过程已应用到迄今为止具有微不足道的零阶预测变量。在本文中，研究了一种更复杂的预测器技术的效果。在包括现实示例在内的各种问题上，使用有限体积和模拟有限差异化进行数值实验。
Recently, the nonlinearity continuation method has been used to numerically solve boundary value problems for steady-state Richards equation. The method can be considered as a predictor-corrector procedure with the simplest form which has been applied to date having a trivial, zeroth-order predictor. In this article, effect of a more sophisticated predictor technique is examined. Numerical experiments are performed with finite volume and mimetic finite difference discretizations on various problems, including real-life examples.
