| E5006 | FATAL ERROR: E5006 | STIFFNESS MATRIX STORAGE BLOCK LIMIT EXCEEDED |
| Cause: | The number of stiffness matrix storage blocks required was greater than 2000. This is caused by not enough memory being allocated to the Program Memory Manager. | |
| Action: | Increase the Model Initialization directive, RAM, to a larger value. Note that values greater than the amount of your system’s available physical memory may degrade performance. Also, consider using either the sparse direct or iterative solver which require less memory and are considerably faster. | |
| Remarks: | See Autodesk Nastran User's Guide, Section 2.1.1, Model Initialization File, for more information on memory management. |
