hi everybody,
I have some barrier and I want to solve my problem axisymmetric. I attach you my result but it's not true, I can't understand why the streamlines go up instead of going right!!!?!?!?? air enter from inlet and out side the barrier is atmosphere, actually air from indoor go to outdoor. and I rotate my model 90 degree to solve the problem axisymmetric. what should I do to preventing the fluid going up??!?? if you rotate it -90 it should operate such as a stack.

thank you mali
but my problem was free convection and I had forgot setting my fluid an ideal gas. |

I think, you could extend calculation domain

my answer can be wrong... but
In my opinion, outflow condition(neumann boundary condition) doesn't likes backflow, so, if you have enough computer resource, how about extend it's length? // my mother-language is not an English, please forgive my grammatical error Cartman. |

thank you Cartman, It's done, I select my density of material a Bussinique model and it give me well solutions. bye. |
