Internal Programming Error

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?

I have got 16 GB RAM. If I run it on my laptop with also 16 GB, i don't get this error message

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.
