Hello, I want to simulate one cylindrical heat pipe with condition 20M w/m^2 on the top only.And we try to use water inside.
I found that there was an example on the web, 'flat_heat_pipe', so I did the same Physics and boundry conditions like that, but 2D Axissymmetric geometry with mesh automatic.
At first, when I just calculated with heat transfer and laminar flow, it works, but after I calculated it with Multiphysics, 'Non-Isothermal Flow', it told me there was an error, maybe something wrong with domain 2 wick part?
I also import my model below, thanks very much for help.
