| Abstract: | 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 im-plemented 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. |
