Field Contents SI Unit Example
EID Unique element identification number.

No default (Integer > 0)

PID A PMASS property identification number.
Specifies an identification number for this property.
Specifies a user-defined string label for this property. 4

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

S1, S2 Scalar point identification numbers.

S1 or S2, but not both, may be blank or zero, indicating a constrained coordinate.

Default = 0 (Integer ≥ 0; S1S2)



  1. Only one scalar mass 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. Scalar mass elements are ignored in heat transfer analysis.
  4. 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.
  5. This card is represented as a spring or mass element in HyperMesh.
