EID |
Unique element identification number. No default (Integer > 0) |
B |
Value of the scalar damper. No default (Real) |
G1, G2 |
Geometric grid point identification number. Default = blank (Integer > 0) |
C1, C2 |
Component number in the displacement coordinate system specified by the CD entry of the GRID data. Default = 0 (0 < Integer < 6) |
1. | Zero or 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. |
2. | Scalar points may be used for G1 and/or G2, (with a corresponding C1 and/or C2 of zero or blank). If only scalar points and/or grounded terminals are involved, it is more efficient to use the CDAMP4 entry. |
3. | This single entry completely defines the element since no material or geometric properties are required. |
4. | The two connection points (G1, C1) and (G2, C2) must be distinct. |
5. | When the SPSYNTAX setting on the SYSSETTING I/O option is set to CHECK (default) or STRICT, it is required for grid/component pairs (G#/C#) that the component be 0 or blank when the grid reference is a scalar point (SPOINT), and that the component be > 1 when the grid reference is a structural grid point (GRID). When SPSYNTAX is set to MIXED, it is allowed for grid/component pairs (G#/C#) that the grid reference be either a scalar point (SPOINT) or a structural grid point (GRID) when the component is 0, 1 or blank; interpreting all of these as 0 for scalar points and as 1 for structural grids. When the component is greater than 1, the grid reference must always be a structural grid (GRID). |
6. | Scalar damper elements are ignored in heat transfer analysis. |
7. | This card is represented as a spring or mass element in HyperMesh. |
