Description: Defines default options for fields 3, 7, 8, and 9 of all GRID entries.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| CP | Identification number of coordinate system in which the location of the grid point is defined. | Integer ≥ 0 or blank | 0 |
| CD | Identification number of coordinate system in which the displacements, degrees of freedom, constraints, and solution vectors are all defined at the grid point. | Integer ≥ 0 or blank | 0 |
| PS | Permanent single-point constraints associated with grid point (any of the digits 1-6 with no imbedded blanks). | Integer ≥ 0 or blank | |
| SEID | Superelement identification number. | Integer ≥ 0 or blank |
Remarks:
- The contents for fields 3, 7, 8, or 9 of this entry are assumed for the corresponding fields of any GRID entry whose field 3, 7, 8, or 9 are blank. If any of these fields on the GRID entry are blank, the default option defined by this entry occurs for that field.
- Only one GRDSET entry may appear in the Bulk Data Section.
- The primary purpose of this entry is to minimize the burden of preparing data for problems with a large amount of repetition.
