Modelling of porous media for scientific simulation and visualization
Brian Wyvill, Leon Fedenczuk · 1996
A new hierarchical method for creating three dimensional models of porous media is presented. The models are based on a stochastic or deterministic octree data structure. Extensions to algorithms for finding connectivity in the octree data structure are also presented. They form a basis for algorithms which are then used to model the physical properties of porous media. These algorithms model fluid interactions in porous networks, and estimate the electrical properties of the models. The simulation results, and the models themselves, are visualized in forms which emphasize their geometrical properties and fluid saturations. The methodology and algorithms form a foundation for a virtual laboratory of porous media where models can be created and simulated. Such a laboratory may be used to test scientific hypotheses and lead to an advance in the understanding of cause and effect relationships in porous media.
