Bulk Data Entry Defines default options for fields 3, 7, and 8 of all GRID entries.

Field Contents SI Unit Example
CP Coordinate system identification number in which the location of the grid point is defined.

(Integer > 0 or blank)

CD Coordinate system identification number in which displacements are measured at grid point.

(Integer > 0 or blank)

PS Permanent single-point constraints associated with grid point (any of the digits 1-6 with no embedded blanks).

(Integer ≥ 0 or blank)



  1. The contents of fields 3, 7, or 8 of this entry are assumed for the corresponding fields of any GRID entry whose field 3, 7, and 8 are blank. If any of these fields on the GRID entry are blank, the default option defined by this entry occurs for that field. If no permanent single-point constraints are desired or one of the coordinate systems is basic, the default may be overridden on the GRID entry by entering zero in the corresponding field. Only one GRDSET entry may appear in the Bulk Data section.
  2. The primary purpose of this entry is to minimize the burden of preparing data for problems with a large amount of repetition (for example, two-dimensional pinned-joint problems).
  3. At least one of the entries CP, CD, or PS must be non-zero.
