14.7.3.5 CellShape

For Standard	RESQML v2.0.1

Used to indicate that all cells are of a uniform topology, i.e., have the same number of nodes per cell. This information is supplied by the RESQML writer to indicate the complexity of the grid geometry, as an aide to the RESQML reader.

If a specific cell shape is not appropriate, then use polyhedral.

BUSINESS RULE: Should be consistent with the actual geometry of the grid.

Name	Data Type	Notes
tetrahedral	External Reference	All grid cells are constrained to have only 4 nodes/cell with 4 faces/cell, 3 nodes/face, 4 nodes/cell for all cells (degeneracy allowed).
pyramidal	External Reference	All grid cells are constrained to have only 5 nodes/cell with 5 faces/cell, with 1 quadrilateral face and 4 triangular faces.
prism	External Reference	All grid cells are constrained to have 6 nodes/cell with 5 faces/cell, with 3 quadrilateral faces and 2 non-adjacent triangular faces, as in a column layer grid with triangular columns.
hexahedral	External Reference	All grid cells are constrained to have 8 nodes/cell with 6 faces/cell, 4 nodes/face, 8 nodes/cell for all cells (degeneracy allowed). Equivalent to IJK grid cells.
polyhedral	External Reference	If the cell geometry is not of a more specific kind, use polyhedral.
