Simply read the NX Nastran output file *.f06 and search for word FATAL, you will have there the reason of the error: you have defined CBUSH element no. 450 where the same node is used twice to orient the element.
*** USER FATAL MESSAGE 350 (IFS350) THE FOLLOWING GRID OR SCALAR POINTS ARE SPECIFIED MORE THAN ONCE ON THE BULK DATA ENTRY SHOWN BELOW: 408 *** USER FATAL MESSAGE 316 (IFPDRV) ILLEGAL DATA ON BULK DATA ENTRY CBUSH User information: See Bulk Data entry description in Section 5 of the NX NASTRAN Quick Reference Guide. If you are using the large field format make sure the number of entries is even. CBUSH 450 8 366 408 408
Editing the element 450 we see the reason of the error:
Simply instead the third-node use the option CSYS = Basic Rectangular, and you are done!.
