Computer-implemented systems and methods are provided for an upscaling approach based on dynamic simulation of a given model. A system and method can be configured such that the accuracy of the upscaled model is continuously monitored via indirect error measures. If the indirect error measures are bigger than a specified tolerance, the upscaled model is dynamically updated with approximate fine-scale information that is reconstructed by a multi-scale finite volume method. Upscaling of multi--phase flow can include flow information in the underlying fine-scale. Adaptive prolongation and restriction operators are applied for flow and transport equations in constructing an approximate fine-scale solution.

La présente invention concerne des systèmes et des procédés informatiques pour une technique dinterpolation basée sur une simulation dynamique dun modèle donné. Un système et un procédé peuvent être configurés de sorte que la précision du modèle interpolé est suivie en continu par des mesures derreurs indirectes. Si les mesures derreurs indirectes sont plus grandes quune tolérance spécifiée, le modèle interpolé est mis à jour dynamiquement avec une information déchelle fine dapproximation qui est reconstruite par un procédé de volumes finis multi-échelles. Linterpolation découlement multiphasique peut comprendre une information découlement dans léchelle fine sous-jacente. Un prolongement adaptatif et des opérateurs de restriction sont appliqués pour des équations découlement et de transport dans la construction dune solution déchelle fine dapproximation.
