CMASS4
Bulk Data Entry Defines a scalar mass element that is connected only to scalar points, without reference to a property entry.

Definitions
| Field | Contents | SI Unit Example | 
|---|---|---|
| EID | Unique element
                                identification number. No default (Integer > 0)  | 
                            |
| M | Scalar mass value. No default (Real)  | 
                            |
| S1, S2 | Scalar point
                                identification numbers. S1 or S2, but not both, may be blank or zero, indicating a constrained coordinate. This is the usual case. Default = 0 (Integer ≥ 0; S1 ≠ S2)  | 
                            
Comments
- Only one scalar mass element may be defined on a single entry.
 - A scalar point specified on this entry does not need to be defined on a SPOINT Bulk Data Entry.
 - This single entry completely defines the element since no material or geometric properties are required.
 - Scalar mass elements are ignored in heat transfer analysis.
 - This card is represented as a spring or mass element in HyperMesh.
