Field Contents SI Unit Example
EID Unique element identification number.

No default (Integer > 0)

PID A PELAS property entry identification number.
Specifies an identification number for this property.
Specifies a user-defined string label for this property. 3

Default = EID (Integer > 0 or <String>)

S1, S2 Scalar point identification numbers.

S1 or S2 may be blank or zero indicating a constrained coordinate.

Default = 0 (Integer ≥ 0; S1S2)



  1. Only one scalar spring element may be defined on a single entry.
  2. A scalar point specified on this entry does not need to be defined on a SPOINT Bulk Data Entry.
  3. String based labels allow for easier visual identification of properties, when being referenced by the elements cards. For more details, refer to String Label Based Input File in the Bulk Data Input File.
  4. This card is represented as a spring or mass element in HyperMesh.
