Nastran NX6, Advanced Simulation File

[alaa4m]

Hi...
I have problem when I model up geometry in Unigraphics NX6 and I export this geometry to Advanced simulation, then mesh it and set up the boundary condition, until everything works o.k., but when I run Solve command, there is no Sim file whritten, then I can't visualize the results.

Anybody can help me?

Note: The liscence file is read by UGSLiscence manger and the program installed properly

Best regards

Hi...
When I solve any problem there is no results file upploaded
automatically in simulation navigator.
But, the results file genrated as f04, f06 and sim format separated. Anyway, those results file are empty.

Any one can help me, thanks
best regards
Alaa

post some error messages, so we can see whats wrong with your model, there are number of things that can go wrong...

Hi bojanv...

Actually, there is no any error message comes up, the monitor windows shows the job finishied, but Nastran generats several file with format F04, F06 and DAT. The files which has foramt F04 and F06 are empty, while file format DAT is filled. I attached picture to see the monitor windows status.

Notice:
I attempted to solve some problems (stress analysis) in Nastran many times before two months ago, there was no problem, everything goes good and I visualized the results in each time, but in this week the program dos'nt show results file in the simulation navigator.

Hello!,
Open the *.F06 file and you will see there the reason of the problem. The *.F06 file (together with the NX Nastran *.LOG, *.F04 & *.OP2 files) is located in the same directoy where your *.prt file is found. Open the *.F06 with a text editor and copy here the lines of the error, make a search for the word FATAL.
Best regards,
Blas.

Hello Blas....

The *.F06 and *.F04 files are empty.
When I open those with text editor, there is no data.
I attached a picture to see all the file situation where
the *.prt file located.

best regards

Hi...
Forthure information

The Nx log file also attached. The results file *.OP2 not
exist where the *.prt exist, I mean not generated.

best regards

Hello!,
NX LOG file is useless at all regarding the NX Nastran error, but I see you manage a long path:

C:\Documents and Settings\aerospace\Skrivbord\Nastran_Kursmaterial\mt15020_nx6015_activities_and_parts\mt15020_nx6015\student_home\parts\test_gearbox\gearbox_housing1_sim1.sim

Make a copy of all model *.prt, *.fem and *.sim files to a simply directory, say D:\MODELS and check if the error persist. Or better create a simply model to see if you have a license problem, this way you can investigate if the error comes from the model, or from the license, or is an installation problem.

Best regards,
Blas.

Hi Blas...

I did as you said, I moved the *.prt file to the root C:/
but the same thing no results file generated, I also created a new model (Cantliver Beam), then exported that modell to advanced simulation (Nastran) to ensure everything done correct from the begning
, the same problem I faced the is no results file, *.OP2 generated where the *.prt exist.

Best regards

Hello!,
Then contact GTAC, you have either a license or installation problem.
