Free Boundary Analysis Set Definition
Description: Defines analysis set (a-set) degrees-of-freedom to be free (c-set) during generalized dynamic reduction or component modes calculations.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| Gi | Grid point identification number(s). | Integer > 0 | Required |
| Ci | Component number of global coordinate. (Up to six unique digits may be placed in the field with no embedded blanks.) | 1 ≤ Integers ≤ 6 | Required |
Remarks:
- If there are no CSETi or BSETi entries present, all a-set points are considered fixed during component mode analysis. If there are only BSETi entries present, any a-set degrees of freedom not listed are placed in the free boundary set (c-set). If there are both BSETi and CSETi entries present, the c-set degrees of freedom are defined by the CSETi entries, and any remaining a-set points are placed in the b-set.
