METHOD OF THREE-DIMENSIONAL SIMULATION OF SPECIFIED HYDROGEOLOGICAL FEATURE IMPLEMENTED IN COMPUTER SYSTEM Russian patent published in 2017 - IPC G06T7/60 

FIELD: information technologies.

SUBSTANCE: pre-simulated feature is virtually broken down into a certain number of layers, then the parametric coordinates of points of boundary contour of the simulated feature and formed layers as a set of points arranged clockwise are determined and stored in the memory, then for each layer interface by respective computing cores a two-dimensional unstructured grids, including a list of nodes coordinates, lists of nodes and cells, are constructed. Then each obtained two-dimensional unstructured grid is broken down into subdomains and the coordinates of nodes, an ordered set of numbers of nodes of each cell and a list of numbers of neighboring cells of each formed subdomain are saved in the memory of the respective computational kernel; then in parallel mode the construction of three-dimensional computational mesh of the specified hydrogeological feature is performed during this process simultaneously through the respective processing kernel from each cell of each formed subdomain of two-dimensional unstructured grid using coordinates points of contours of cells along the z-axis a polyhedron is formed, then simultaneously in each subregion the boundary conditions for each polyhedron formed by additional specifying of planes are determined that are common with neighboring polyhedra. Then produce each polyhedron is broken down in a certain manner along Z-axis in a certain number of cells, then additionally the boundary of the cell and faces polyhedra in contact with the surfaces of the layers are specified, then in the respective computer kernel the coordinates of nodes, lists of plane nodes, lists of planes of cells of each polyhedron of each formed subregion of the three-dimensional computational grid are saved.

EFFECT: improvement of accuracy of simulation of specified feature.
