Multigrid Methods for Flow and Transport Processes in Porous Media

Forward and inverse modeling of flow and transport in porous media poses a wide variety of computational challenges. Porous media are often highly heterogeneous, thus producing a great deal of variation and discontinuities in hydraulic conductivity. The model may also contain multiple phases, thus posing additional computational difficulties. The speakers in this session will show that multigrid methods are very effective tools for simulation computations. On the other hand, inverse modeling problems, too, can be attacked by a multigrid approach, which is demonstrated to lead to highly efficient system identification methods.
