Nastran Explicit nonlinear simulation error
Nastran Explicit nonlinear simulation error
(OP)
Hi everybody,
I am now using Msc Nastran and Patran to simulate a drop test of a bottle. However, the simulation cannot run. I have checked the f06 file. The following sentences are shown:
M O D E L S U M M A R Y
NUMBER OF GRID POINTS = 2667
NUMBER OF CQUAD4 ELEMENTS = 144
0FATAL ERROR
1 * * * END OF JOB * * *
No Symbolic Replacement variables or values were specified.
Does anybody know how to fix it? The simulation is very important to me as it is a part of my final year project.
Attached please find f06 and bdf file for reference.

Thank you all of you.

Try to run the file with the following entries for TSTEPNL

Sorry about that because I am a new user of Nastran.

From where you initially set it. From there, you can edit it. Or, you can simply change the settings to the *.nas file (or dat or bdf etc)
