COMPUTER IMPLEMENTED METHOD FOR MANIPULATING A NUMERICAL MODEL OF A 3D DOMAIN

摘要

The present invention is related to a computer implemented method for manipulating a numerical model of a 3D domain, said numerical model comprising geometrical entities such as layers, fractures, discontinuities, facies, etc., being identified as geometrical entities because they can be defined by its shape. The resulting data storage block is very large. The management of such large data bases or data storage block may be unaffordable as simple operations over one or more geometrical entities require the processing of the entire data base. The method provides an efficient management of the data base by a set of specific lists of indexing keys increasing the speed of access, for instance for writing and reading operations, for one or more determined geometrical entities.
