Hello,

 I am trying to perform an optimization in a carbon fiber monocoque. I am with the first phase, the free sizing. But I have the following error:

 

*** ERROR # 583 ***
 Missing objective, DESGLB and DESSUB data must be used together with
 an objective function defined by DESOBJ, MINMAX, or MAXMIN.

 

I have been checking all the optimization parameters and I have defined all of them (see picture), so I do not know what it is failing. Anybody could help me please? Thank you

    Could you please share the .out file of the run?

    Unable to find the cause from the shared .out file. It seems you are using the latest version of OptiStruct. It would be great If you could also share complete .fem and .out file of the run.

    Yes, I am using the latest version. 

     

    I send to you via dropbox the files. The forum do not let me upload

    Thanks for sharing the files.Shared .fem file gives different error in my machine.Which i feel is related to FE modelling.

     

     *** ERROR # 605 ***
     Element 808155 is referenced by STACK 1 (on PLY 20) and by
     STACK 2 (on PLY 28) simultaneously

     

    Could you give a try running same file in other directory and with different file name.

    I have made the model again and run in other computer. I have had the same error but it has been easy to solved it.

     

    So, the model is now run correctly.

     

    Thank you very much

    Hello, I met the error recently, too. My situation is totally the same with yours except that I haven't define the 'optimization controls'.

    You say it's easy to solve it. Could you please tell me what the problem is?:)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />
