| E5073 | FATAL ERROR: E5073 | NON-ZERO LOAD VECTOR REQUIRED FOR NONLINEAR ANALYSIS |
| Cause: | In a NONLINEAR solution, a non-zero global load vector is required to perform nonlinear iterations. This error is usually the result of either not referencing or referencing non-existing LOAD, SPC, or TEMPERATURE sets in the Case Control Section. | |
| Action: | Correct the model loading. | |
| Remarks: | See Autodesk Nastran Reference Guide, Section 3, Case Control, for command format. |
