Abstract
B022 PARALLEL ANISOTROPIC CARTESIAN GRID ADAPTATION FOR IN-SITU COMBUSTION SIMULATIONS Abstract 1 A parallel anisotropic adaptive Cartesian grid method for simulating in-situ combustion processes is presented. It is based on local cell-based grid refinement that allow fast transition from coarse to fine grids with very few extra cells. The anisotropic refinements allow for an improved alignment of the grid with important features in both the flow and the geology. The pressure equation is discretized on these anisotropic cells with a novel higher order compact finite volume method. The fluxes are computed with a second order accurate finite difference approximation combined
