Hi！I am using Optistruct to conduct a transient NVH simulation, there's an error: "Not enough memory. (error code -2)". My run option is "in-core, -nt 18".

As you can see, the “.Out” file shows Estimated Memory (RAM) for In-Core Solution is 85002 MB and my computer has enough memory(248073 MB RAM) .

Could you please advise what should I do? Simplify my model or choose “-core（out/min）” run option? Thanks a lot!

    You can try both, -core out as well as having coarse mesh simplified model.

    Even reducing the output also helps.

    Can you upload the complete .out and .stat file to check few details?
