Transient Initial Condition
Description: Defines values for initial conditions of variables used in transient response analysis. Displacement, velocity, and acceleration may be specified at independent degrees of freedom.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| SID | Set identification number. | Integer > 0 | Required |
| Pi | Grid point identification number. | Integer > 0 | Required |
| Ci | Component number of global coordinate (up to six unique digits may be placed in the field with no embedded blanks). | 0 ≤ Integer ≤ 6 | Required |
| U0 | Initial displacement. | Real | 0.0 |
| V0 | Initial velocity. | Real | 0.0 |
| A0 | Initial acceleration. | Real | 0.0 |
Remarks:
- Transient initial condition sets must be selected with the Case Control command IC = SID.
- If no TIC set id selected in the Case Control Section, all initial conditions are assumed zero.
- Initial conditions for coordinates not specified on TIC cards will be assumed zero.
