Description
The CELAS2 entry defines a scalar spring element without reference to a property entry.
Format
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| CELAS2 | EID | K | G1 | C1 | G2 | C2 |
Example
| CELAS2 | 124 | 1.0+4 | 44 | 5 | 45 | 5 |
| Field | Definition | Type | Default |
|---|---|---|---|
| EID | Element identification number. | Integer > 0 | Required |
| K | Stiffness value. | Real | Required |
| G1, G2 | Grid point identification numbers of connection points. | Integer > 0 | See Remark 2 |
| C1, C2 | Component numbers. | 0 ≤ Integer ≤ 6 | See Remark 2 |
Remarks
- Element identification numbers must be unique with respect to all other element identification numbers.
- A blank may be used to indicate a grounded terminal G1 or G2 with a corresponding blank or zero C1 or C2. A grounded terminal is a point whose displacement is constrained to zero.
- This single entry completely defines the element since no material or geometric properties are required.
- The two connection points (G1, C1) and (G2, C2), must be distinct.
- If Gi refers to a grid point, then Ci refers to component numbers in the displacement coordinate system specified by CD on the GRID entry.
