Description
The MOMENT entry defines a moment at a grid point by specifying a vector.
Format
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
MOMENT | SID | G | CID | M | N1 | N2 | N3 |
Example
MOMENT | 3 | 441 | 4 | 10.0 | 1.0 | -1.0 | 0.0 |
Field | Definition | Type | Default |
---|---|---|---|
SID | Load set identification number. | Integer > 0 | Required |
G | Grid point identification number. | Integer > 0 | Required |
CID | Coordinate system identification number. | Integer ≥ 0 or blank | 0 |
M | Moment vector scale factor. | Real | Required |
N1, N2, N3 |
Moment vector components measured in coordinate system defined by CID. |
Real | Required; must have at least one nonzero component |
Remarks
- The moment applied to grid point G is given by
where
is the vector defined in fields 6, 7 and 8.
- Load sets must be selected in the Case Control Section (LOAD = SID).
- A CID of zero references the basic coordinate system.
