A 1D grid defining a 1D index. Each grid specifies a) the axis points, b) whether the grid forms a loop or not, and c) the coordinates to be used to describe each grid node.

grid_1d_s (PK, M: CHAR VARYING(19))

Surrogate key of the table.


connected (M: CHAR(1))

grid_1d.connected
This describes the behavior where the last point in the grid is connected to the first point of the grid. If TRUE then the last point of the grid is connected to the first point (i.e., the grid connects as a loop and the first point may be reached by going past the last point). If FALSE, the first and last points are unconnected and the first point may not be directly reached from the last point. This behavior does not impact the population of a subset of the grid (e.g., if a connected 30 point grid is populated from points 5 to 20, this does NOT mean that point 20 connects to point 5).


grid_or_mesh_name (M: CHAR VARYING(40))

grid_or_mesh.name
The name or identifier of this grid.


entity_type_nm (M: CHAR VARYING(40))

Column that contains the name of the entity that this row is an instance of in case a table represents multiple entities. Possible values are: grid_1d_equal, grid_1d_parametric, grid_1d_unequal.


coordinate_value (O: CHAR VARYING(16))

grid_1d_unequal.coordinate_value
The axis coordinate values, indexed by point number.


description (O: CHAR VARYING(2000))

grid_or_mesh.description
A description of the grid.


missing_element (O: CHAR VARYING(16))

grid_structured.missing_element
This indicates the missing elements of the structured grid. Missing elements are excluded from the grid and cannot be assigned properties. The highest order of elements allowed in the grid must be used (i.e., cells in a 3D grid). For grids composed of other grids, the behavior is cumulative with the composed grid inheriting the behavior of the component grids. For example, in seismic, a 2D binset grid may have missing elemets such that the grid is "L" shaped. If a 3D grid (cube) is formed using the 2D binset grid and a 1D vertical time grid then the "columns" of the cube should be considered missing.


origin (O: FLOAT)
origin_u (FNK, O: CHAR VARYING(15))

grid_1d_equal.origin
The coordinate value of the first point of the axis.
origin_u: Defines the unit of measure. Defines a foreign key to table r_uom.


point_count (O: INTEGER)

grid_1d_equal.point_count
The number of points of the axis.
grid_1d_parametric.point_count
The number of points of the axis.


step (O: FLOAT)
step_u (FNK, O: CHAR VARYING(15))

grid_1d_equal.step
The increase in coordinate value between two successive axis points.
step_u: Defines the unit of measure. Defines a foreign key to table r_uom.


cord_sys_axis_s (FSK, O: CHAR VARYING(19))

grid_1d_equal.coordinate_system_axis
This designates the coordinate system axis used to describe the origin and step of the grid 1D equal. This axis defines the property used for the origin and step.
Defines a foreign key to table cord_sys_axis.
