Description
The FORCE1 entry defines a static load 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 |
FORCE1 | SID | G | F | G1 | G2 |
Example
FORCE1 | 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 |
F | Load magnitude. | Real | Required |
G1, G2 | Grid point identification numbers. | Integer > 0; G1 ≠ G2 | Required |
Remarks
- The static load applied to grid point G is given by:
In the above equation,
is a unit vector parallel to a vector for G1 to G2.
- Load sets must be selected in the Case Control Section (LOAD = SID).
