Needing help in simulating Natural convection in a pool
 

hi everyone.
i want to simulate natural convection in an outdoor pool with fluent,the case is a tank with 2 tube connected to a coil and it is 3d-steady filled with water.I use boussinesq for density,but i cant get the right answer.The pressure contour and temperature contour shows no logical answer.i would appreciate any suggestion and help.tnx

In Boussinesq is not showed static pressure. Write for me private message, I will try to help for You.

bcs?
 

This is a public forum and it is better to help in public for everyone else to be able to assist and learn from the discussion.

May I ask the boundary conditions, obtained results and expected results here?

The problem is showing circulation of water by natural convection in a pool(hot tub) with no pump or any unnatural force(like pumps).i thought maybe temperature bc may help me but the answer showing no circulation or even hotter tank!i need help both in method and bc.
p.s this link shows the exact diagram of what i want to do.

Could you send some pictures of your results? Is there temperature gradient of any kind?
