Reservoir simulation involves to compute dynamic flow of different phases ina porous medium. The initial state of the reservoir is usually precomputed viageo-statistics methods, extrapolating measures of the terrain. so, the inputof reservoir simulation is given as a fine mesh containing heterogeneous dataIn this paper, we describe an...

This paper describes an algorithm designed for the automatic coarsening of three-dimensional unstructured simplicial meshes. This algorithm can handle very anisotropic meshes like the ones typically used to capture the boundary layers in CFD with Low Reynolds turbulence modeling that can have aspect ratio as high as 104. It is based on the...
