    What setting I need to set to model a confined space.

    For example I wish to simulate natural convection
    in a rectangular cavity.

    When I do it I also gives result outside the rectangular
    box, though I insulated.

    Any good idea? Thanks.

    I have included a file, please try it
    and also suggest any thing to work better.

    You need to increase the thickness of the walls to avoid the leakage. This is because we use only a 100×100 grid, not enough to handle thin walls. I attached a revised model that has no leak.

    It is slightly better. But when I plot results I do not want any result outside the box. How to avoid. Is it considering radiation effect also even if I give emissivity as zero?

    Thanks again.

    Show me your results. Perhaps I didn’t run long enough to see leakage.
