Ask admins to delete other two themes.
This problem may be caused by some instalation errors, look at similar themes:
When I run your model I dont get this error, instead Nastran write in f06 file that:
***ALERT: TABLEDx 2 does not span the range of solution times.
Your load function is from 0 to 0,5 sec. In your analisys you select 1 time step 1 sec long - it is wrong, i think you not definer nonlinear solution paraqmeters at all. Brake solution time to 50-100 timesteps at begining, if you dont get convergence - use more time steps. Your total solution time must be not great as load function duration - in your case 0,5 sec. Use some advanced options - auto timestepping - solver automaticaly reduce timestep when it dont get convergence. You can use extra time steps, like 10x0,001sec+100x0,02sec+10x0,5sec to use small time step only at time when you need it. In advanced nonlinear static time isnt real, it used only to apply load incrementaly.
Look like ok. Repeat third time I sure for 95% "advlin error" is caused by instalation error, so you cant proceed to calculation. Reinstall NX, ask administrator or NX salesman for help.
It is something wrong with translation from NX to Nastran dat file. To define timestep you must use TSTEP card.
TSTEP 109 50 .01 1
50 steps, 0,01 time interval. There is no TSTEP card in your .dat file. Wait for someone who have NX to explain what is wrong in simulation setting. I only read dat.file.
