Hi everyone!

I am working with fluent to simulate the atmosfere, but I really can't seem to find the best wall boundary condition witch will be more real to our atmosfere. can anyone advice me?

Thanks in advance

Hi!

what do you mean with wall boundary condition? are you talking about the inputs once you choose it's a wall or the boundary condition in general for the ground? THis is interesting, but very hard to simulate, isn´t it? If you are talking about the upper layer of the atmosphere, I'd choose a pressure far field.

Thanks Nestor

In fact it was a small mistake, I really wanted to write "which"!

when I said "Wall Boundary Condition" I actually mean the boundary condition in general! for example, fluent presents boundary tipes such as "interior", "interface" .... and I really don´t no which to choose!

gracias

I am also doing those modellings. Velocity inlet; outlet or pressure outlet (almost the same!) at the top symetry and laterally you should use also symetry.....if it applies. At the groung...wall of course
