Description
The MOMENT1 entry defines a moment at a grid point by specification of a value and two grid points that determine the direction.
Format
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| MOMENT1 | SID | G | M | G1 | G2 |
Example
| MOMENT1 | 3 | 141 | -4.5 | 10 | 11 |
| Field | Definition | Type | Default |
|---|---|---|---|
| SID | Load set identification number. | Integer > 0 | Required |
| G | Grid point identification number. | Integer > 0 | Required |
| M | Moment magnitude. | Real | Required |
| G1, G2 |
Moment vector components measured in coordinate system defined by CID. |
Integer > 0; G1 = G2 | Required |
Remarks
- The moment applied to grid point G is given by
where
is a unit vector parallel to a vector for G1 to G2.
- Load sets must be selected in the Case Control Section (LOAD = SID).
