Field	Contents	SI Unit Example
`EID`	Unique element identification number. No default (Integer > 0)
`PID`	PDAMP property entry identification number. Default = EID (Integer > 0)
`G1`, `G2`	Geometric grid point or scalar point identification number. Default = 0 (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)

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.
Scalar points may be used for G1 and/or G2, (with 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 CDAMP3 entry.
The two connection points (G1, C1) and (G2, C2) must be distinct.
A scalar point specified on this entry does not need to be defined on a SPOINT Bulk Data Entry.
When the SPSYNTAX setting on the SYSSETTING I/O Options Entry 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).
Scalar damper elements are ignored in heat transfer analysis.
