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. – Marsup Attachments:You must be logged in to view attached files.

I attached a revised model that has no leak. Attachments:You must be logged in to view attached files. March 24, 2019 at 5:09 am #211 arasukParticipant 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. Arasu March 24, 2019 at 1:31 pm #212 Charles XieKeymaster Show me your results. Perhaps I didn’t run long enough to see leakage.
