| T2062 | WARNING: T2062 | ELEMENT MASS MATRIX IS NON-POSITIVE DEFINITE |
| Cause: | The generated mass matrix for the specified CONM1 or CONM2 Bulk Data entry was non-positive definite. One or more of the principal masses or inertias was negative. | |
| Action: | For CONM1 elements check that the diagonal mass matrix values specified on the Bulk Data entry are positive. For CONM2 elements check that the mass value and diagonal mass moments of inertia are positive. | |
| Remarks: | See Autodesk Nastran Reference Guide, Section 4, Bulk Data, for entry format. |
