nastran error message

nastran error message

nastran error message

(OP)
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

Hello!,
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,
Blas.

Hello,

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
SA

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,
Blas.

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.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
