11.14 Truncated Column-Layer Grid Representation
|For Standard||RESQML v2.0.1|
RESQML supports two truncated column-layer grid representations, which may be based upon either 1) IJK or 2) unstructured column-layer grid geometry. These grids are very similar to the underlying fundamental grids but with the extension to allow cells to be truncated and split along the fault surfaces of a structural framework. The truncated cells have more faces than in the underlying grid, and the portions of the cell volumes that are split create additional split cells. The resulting grid cell topology has 3+1 indices for truncated IJK grids and 2+1 indices for truncated unstructured column-layer grids.
Figure 11.14-1 shows the grid representation. Its elements are similar or identical to those already described. Unlike other grid classes, explicit grid geometry is required and the truncated grids do not support geometry-free, block-centered representations.
