Field	Definition	Type	Default
EID	Element identification number.	Integer > 0	Required
PID	Property identification number of a PELAS entry.	Integer > 0	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

1. Element identification numbers must be unique with respect to all other element identification numbers.
2. 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.
3. The two connection points (G1, C1) and (G2, C2), must be distinct.
4. 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.
