    Hi Ben,

     

    FEKO ties to minimise the amount of RAM that is used. Is there a reason why you want to use more RAM?

    The easiest way to increase RAM usage is to use a finer mesh - but deepening on how you originally set up the mesh, there may not be any improvement in accuracy doing this. Have a look through some of the other posts on the forum on mesh convergence studies to get more details.

    What's about your simulation size? Number of node/elements?

    If your model is NOT-BIG-ENOUGH, that's logic the simulation needs small memory, right?

    Is there a case whereby FEKO only allowed 12GB, but his simulation needed at least 25GB of RAM (or in-core memory) to run on his 128GB RAM computer?
