coreOUT Problem

I'm attempting to run my sim with the '-coreOUT' command in run options. It will go through the preprocessing within Hypermesh, but then it will not actually launch the Optistruct window as it normally does. My PC can't handle the memory requirements, so I must run it as an Out-of-Core sim. Any solutions?

    -core out  >> don't forget the space between core and out.

     

    Have in mind that out-of-core is much slower than the core in.

    Maybe reviwning your model size/refinement.

    Ahhh. I haven't been using the space. Thank you so much.

    Actually, let me ask you this:

     

    -ncpu 4 -core out -fixlen 16000

     

    and the solver won't launch. But it will launch with just -core out. Any idea for why this happens?

    not sure.

     

    avoid using names and folders with spaces and special characters.

    F:/Aaron/Documents/Hsiao Thesis/Hypermesh/2X2 RUN A.fem

     

    try 

    -nproc 4 -core out -fixlen 16000

    by the way, make sure you're running in a local disk and not using network drives.

    Try to use an HPC plateform if you have a heavy FE model ...
