nastran error message

nastran error message

nastran error message

I use nx6 with nx nastran on windows7 64.  When I run the structural analyse with adaptivity, nastran returned to me error message "there is a problem opening result file". Usualy results are available, but adaptivity proces is not run. May you somebody know, where is problem?

Thanks for help.

RE: nastran error message

Open the *.F06 file and tell us what you see there, search for the word FATAL. Also, take a look to *.LOG file to see nay license error.
Best regards,

RE: nastran error message


Here are my *.log and *.F06 file (both in f06 file). May you can see where is the problem.
The system returned to me this error sometimes immediately, sometimes after the first or second iteration. But never come to the desired number of iterations or the desired accuracy.

Best regards

RE: nastran error message

Dear SA,
I do not see any track of error, then what I suggest is to see if the model can be solved as a normal run, not adaptive (I do not run at all Adaptivity, this is for marketing, not  a pratical tool in engineering day-by-day). If normal run ran OK, then change the solver, instead Iterative use Direct Sparse (well, desactivate the Iterative solver), I see it is a small model so no problem with memory. If failed again then send the model to SIEMENS GTAC for inspection and they will tell you where the error is.
Best regards,

Hello Blas

Thank you for your advice. When run a normal ran (without adaptivity  and interative), then is OK. But, because I am rather new, how can I refine mesh more then less automaticaly.
