In geometry, a corner-point grid is a tessellation an Euclidean 3D volume where the base cell has 6 faces. A set of straight lines defined by their end points define the pillars of the corner-point grid. The pillars have a lexiographical ordering that determines neigbouring pillars. On each pillar, a constant number of nodes (corner-points) is defined. A corner-point cell is now the volume between 4 neighbouring pillars and two neighbouring points on each pillar.

  • In geometry, a corner-point grid is a tessellation an Euclidean 3D volume where the base cell has 6 faces. A set of straight lines defined by their end points define the pillars of the corner-point grid. The pillars have a lexiographical ordering that determines neigbouring pillars. On each pillar, a constant number of nodes (corner-points) is defined. A corner-point cell is now the volume between 4 neighbouring pillars and two neighbouring points on each pillar. Each cell can be identified by integer coordinates <math>(i,j,k)</math>, where the <math>k</math> coordinate runs along the pillars, and <math>i</math> and <math>j</math> span each layer. The cells are ordered naturally, where the index <math>i</math> runs the fastest and <math>k</math> the slowest. In the special case of all pillars being vertical, the top and bottom face of each corner-point cell are described by bilinear surfaces and the side faces are planes. Corner-point grids are supported by most reservoir simulation software, and has become an industry standard.
