simulating wind over terrain

yairsuari · September 14, 2010, 06:56

Dear foamers
i am thinking of using openfoam to simulate wind flow over terrain (to predict wind pattern at sailing events venues).
the method i thought of using is by inserting boundary conditions for different velocity and direction cases, running for a few hours and look at the stabilized wind.
1. do you think its possible
2. i am thinking of using only pressure and velocity field, no temperature, will the results be too distorted?
3. how do i generate my mesh?

4. just an attempt, has anyone done this before?

hey, did u do it? what was the result..i also want to do it to design a wind turbine..

have u tried the actuator disk tutorial in 1.7 wind solver??
It can be found here :
OpenFOAM-1.7.x/tutorials/incompressible/simpleWindFoam

it has simulation of 2 wind turbines on 2 hills with wind blowing.

sorry but i never got to doing it (not with openfoam)
