摘要
结合变网格和特征有限元方法来处理多孔介质中可混溶流体驱动模型问题.在不同的时间层采用不同的有限元空间,在需要时可以进行加密或稀疏网格,进行基函数调整.并对算法做出了误差估计.
A method for numerically solving miscible displacement in porous media is presented and analyzed using a combination of the method of characteristics with the dynamic finite-element method. Different numbers of elements and basis functions are implemented at different levels. It makes the grid refinements or non-refinements and function adjustments possible at any necessary time. Convergence analysis and error estimates are established.
