Hello,
have you find a solution for 3d convection?

I want to simulate natural convection in 3D; i was taken the same parameters like this video
"https://www.youtube.com/watch?v=ThJ3VYhTwMI"
in 2d it's ok , i get a rolls but in 3d fluent doesn't converge.

"Sorry for my english"

I have tried natural convection in 3D a lot. I could not get any convergence. The problem lies with the application of correct boundary condition like symmetry/peridic etc. First get a convergence for 2D problem then if 'necessary' then go for 3D.
