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,
