Indexable grid elements to which point geometry may be attached to describe additional grid geometry.

Name	Data Type	Notes
cells	External Reference	Geometry may be attached to cells to distort the geometry of that specific cell, only (finite element grid).
edges	External Reference	Geometry may be attached to edges to distort the geometry of all cells that refer to that edge (finite element grid). BUSINESS RULE: The edges indexing must be known or defined in the grid representation if geometry is attached to the edges.
faces	External Reference	Geometry may be attached to faces to distort the geometry of all cells that refer to that face (finite element grid). BUSINESS RULE: The faces indexing must be known or defined in the grid representation if geometry is attached to the faces.
hinge node faces	External Reference	For column layer grids, these are the K faces. For unstructured grids these faces are enumerated as the hinge node faces.
nodes	External Reference	Additional grid geometry may be attached to split or truncated node patches for column layer grids. All other node geometry attachment should be done through the Points array of the AbstractGridGeometry, not through the additional grid geometry.
radial origin polyline	External Reference	NKL points must be attached to the radial origin polyline for a grid with radial interpolation. BUSINESS RULE: The optional radialGridIsComplete element must be defined in the grid representation if geometry is attached to the radial origin polyline.
subnodes	External Reference	Geometry may be attached to subnodes to distort the geometry of all cells that refer to that subnode (finite element grid). BUSINESS RULE: An optional subnode patch object must be defined in the grid representation if geometry is attached to the subnodes.
