i am doing modal analysis study on BIW with nastran solver.

  1. i have successfully link nastran solver to the hyperstdy and launched one test run. that model has run time approx.10 min.

          for this model hyperstudy successfully extracted required results.

 

     0.2  but when i launched my biw model for the analysis (which has run time approx. 1 hours) through hyperstudy.

          it try to extract results before completing the simulation .it close the nastran window before run completion.

 

 

you can see in below pic.

execution and extraction in green mark.

but run is not competed. and no output files are generated.

see the pic. below. all output files are in 0Kb. e.g.  .po2 and .pch files

pic from file explo.

note: model is runnable and print all the results when launched directly through nastran.

but when i use hyperstudy for launching nastran run ,it is giving this issue.

 

Thanks for the help

    Hello Mr. Zambre,

    Thank you for contacting HyperStudy Support.

     

    What is the solver script you're using to launch Nastran? What are the arguments?

    Just in case it's useful for you. I'm sharing this link.

    Write Solver Scripts (altair.com)

     

     

    Kind Regards,

    Paola Alvarez.

    I am running the hyperstudy with nastran on  my local system.

    since i am using nastran on local system , I just map the path of .exe file in solver execution script, and no change in solver input argument.


    with this settings small models (run time 10mins) print out all the results successfully. 

    but big models gives issue.(run time 60mins)

     

    Thanks
