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
