Abstract:
1. A method comprising: in a computing system, providing, in a geological domain coordinate system, a conformal mesh, conformal to geological discontinuities of a geological model, that comprises depositional domain coordinates associated with a depositional domain coordinate system; in the computing system, providing, in the depositional domain coordinate system, an initial, at least vertically structured, multidimensional grid that comprises initial nodes that define grid cells; analyzing, using the computing system, the conformal mesh to identify a set of grid cells of the initial grid traversed by the geological discontinuities; splitting, using the computing system, each of the grid cells in the set to form sub cells, each of the sub cells defined at least in part by one or more new nodes; and assigning, using the computing system, geological domain coordinates associated with the geological domain coordinate system to at least the new nodes to generate a final grid that comprises the initial nodes, the new nodes and geological domain coordinates associated with the geological domain coordinate system.
