Steve (et al):
I have been using add_pload2 with a pressure and a single EID. pynastran makes a line like
$RIGHT OUTBOARD WING DISTRIBUTED PRESSURE LOAD ON UPPER SURFACE                
                              PLOAD2         4.0064599    3137    THRU    3137
See the THRU has EID2 = EID1. MSC Nastran doesn't complain, but NX Nastran cries about
 *** USER FATAL MESSAGE 316 (IFPDRV)
     ILLEGAL DATA ON BULK DATA ENTRY PLOAD2  
 PLOAD2         4.0064599    3137    THRU    3137
Both QRGs say 
for the “THRU” option,
EID1 < EID2
Can you make pynastran stop doing that? I need to start running NX Nastran more.
Sincerely,
Clark
