摘要
本文导出二维的土壤溶质输运方程的有限体积元格式,并分析其误差.通过数值例子说明,有限体积元格式比有限元格式稳定.
In this paper, a finite volume element (FVE) formulation for two-dimension solute transport problems is derived, error estimates between FVE solutions and accurate solutions are provided. It is shown by numerical examples that FVE formulation is stabler that finite element formulation for solving two-dimension solute transport problems,
