    Hello,

    I am wondering what GPU hardware would be required to run an OpenFoam case with 40m (40.000.000) cells?

    I assume menory will be the bottleneck but I don’t know enough about GPU computing to come up with an estimate.

    Could mixed precision help to reduce the requirements?

    Hi Klaus,

    this depends a lot on your specific case. There is no general rule on memory consumption for 40M cells.
