Method for generating a hex-dominant mesh of a geometrically complex basin

摘要

The method involves generating a hex-dominant mesh of an underground environment by generating cells by creating connections between nodes of surface elements of three-dimensional gridded surfaces. The mesh is generated by detecting the nodes of the first gridded surface, by connecting each node of a detected non-gridded surface with the node in the second gridded surface having same coordinates, by connecting each node of the first gridded surface with a detected break portion and by regulating the cells with two vertices. An independent claim is also included for a method for operating an underground environment.
