Hello,

 

I'm trying to run a non-linear static analysis with Optistruct 2019. However, I always get this error message:

 

 *** INTERNAL PROGRAMMING ERROR ***
   in file 'malloc_1.c', at location # 723.
  
   Dyn_array failed allocation for 2.528657e+03 MB

 

 

Thank you in advance.

    It looks like the memory allocation issue. How much RAM do you have?

    Not really. In your out file, you have ONLY 12420 MB Ram. Have a look at this warning: 

      *** WARNING: The amount of allocated memory exceeds available RAM - this may cause significant slowing down of solution progress due to the swapping out memory to the swap file. It is recommended to use out-of-core solution to reduce memory requirements.
