... is solved for all unknowns (i.e., pressure and saturation), the solution at ADM resolution is prolonged back to fine-scale resolution in order to obtain an approximated fine-scale solution. This dynamic multilevel system employs the fine-scale grid cells only at the sharp gradient of the solution (e.g...

... approach was needed to account for their effect. The computational resources required for dynamic simulation and model run times were very large. The smallest dynamic model had close to 4 million grid cells. The complexity of the structure (many non-neighbour connections) and fluid system (free gas...
