INTERNAL PROGRAMMING ERROR # 8016

Recommended Posts

Hi guys,

I'm doing a shape optimization on some elements of a 2D Pshell and a size optimization of the shell with optistructoptions : -nt=8 -ln=12000 and i've got an error at the end of the iteration 0 :

 

 ****  Error 8016 in datamr() during "expand" operation.
 
     Data block name "ielmlstsol".
 
     Current memory allocation  2864 MB,
    Unused memory              2510 MB,
    Number of blocks: 576 used, 22 free.
 
     Expanding from 1 MB to 23 MB
 
     Need at least 22 MB free (1 MB more than allocated).

 *** INTERNAL PROGRAMMING ERROR # 8020 ***
 Failed database modify command:  Expanding array ielmlstsol.'
 * DATAMANAGER ERROR in subroutine "EXPAND".

Here is the .out file if needed

Thanks in advance,

Frederic.

I currently use the OptiStruct  Version 2017.2.0.13. isn't it the last version? If not i will ask to my IT service for an update  but it can take some time. I'll back to you when it's done. Thank you for your quick answer.

Frederic.

A similar error with nonlinear case is reported with 2017.2 and was fixed in 2017.2.2

 

Please update and check if that helps...
