A method is provided for simulating a physical process such as fluid flow in porous media by performing a fine-grid calculation of the process in a medium and reusing the fine grid solution in subsequent coarse-grid calculations. For fluid flow in subsurface formations, the method may be applied to optimize upscaled calculation grids formed from geologic models. The method decreases the cost of optimizing a grid to simulate a physical process that is mathematically described by the diffusion equation.
L'invention concerne un procédé de simulation d'un processus physique tel que le débit de fluide dans des supports poreux, lequel procédé consiste à effectuer un calcul de grille fine du processus dans un milieu et à réutiliser la solution de grille fine dans des calculs de grille grossière subséquents. Pour un débit de fluide dans des formations souterraines, le procédé peut être appliqué pour optimiser les grilles de calcul interpolées formées à partir des modèles géologiques. Le procédé permet de réduire le coût d'optimisation d'une grille pour simuler un processus physique qui est décrit mathématiquement par l'équation de diffusion.
