14.7.3.58 UnstructuredColumnLayerGridGeometry

Description of the geometry of an unstructured column-layer grid, e.g., parity and pinch, together with its supporting topology.

Unstructured column-layer cell geometry is derived from column-layer cell geometry and hence is based upon nodes on coordinate lines.

Geometry is contained within the representation of a grid.

Table 14.7.3.58-1 Attributes
Name	Data Type	Notes
ColumnIsRightHanded	AbstractBooleanArray	List of columns that are right handed. Right handedness is evaluated following the pillar order and the K-direction tangent vector for each column.
ColumnShape	ColumnShape
PillarCount	positiveInteger	Number of pillars in the grid. Must be positive. Pillars are used to describe the shape of the columns in the grid.
PillarsPerColumn	ResqmlJaggedArray	List of pillars for each column. The pillars define the corners of each column. The number of pillars per column can be obtained from the offsets in the first list-of-lists array. BUSINESS RULE: The length of the first array in the list -of-lists construction must equal the columnCount.
