# 14.7.3.5 CellShape

Topic Version | 1 | Published | 09/11/2015 | |

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.

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. |
