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?

    Both the files are showing issue with memory.

    You can try running with high RAM machine.
