| E5049 | WARNING: E5049 | SINGULARITY DETECTED AT GRID id COMPONENT n |
| Cause: | A singularity has been detected in the stiffness matrix during the decomposition portion of the Sturm sequence check. | |
| Action: | Investigate the degree of freedom at which the singularity occurred for a lack of stiffness. Also, check your model for a lack of constraint. | |
| Remarks: | See messages E5000 and E5044 for more information. If this message occurred during a nonlinear iteration, see message E5048 above and E5077 below. |
