【摘要】 将有限体积元法与特征方向法结合起来,针对对流占优的扩散方程构造了全离散的特征-有限体积元格式,并进行了理论分析,得到了近似解与原问题真解的H1模误差估计,并给出数值算例.更多还原

【Abstract】 The finite volume element method is conbined with the method of characteristics for the convection-dominated diffusion problems in this paper.By detailed theoretical analysis,optimal order H~1 norm error estimates are obtained between the exact solution of original problem and the solution of these fully discrete schemes.更多还原
