| T2071 | FATAL ERROR: T2071 | MODIFIED ELEMENT ORIENTATION NOT PERMITTED FOR ELEMENT TYPE |
| Cause: | A PCOMPS Bulk Data entry was referenced by a CPENTA element with the PCOMPS XZDIR field set to a value other than 13. Only the CHEXA element supports non-default XZDIR values. | |
| Action: | Change the PCOMPS XZDIR field to 13 and verify the CPENTA element is properly oriented in the mesh so the ply stack direction is from one triangular face to the other. | |
| Remarks: | See Autodesk Nastran Reference Guide, Section 4, Bulk Data, for entry format. |
