Boundary condition for open (infinity) sky??

July 13, 2007, 08:10

Good afternoon,I am an engineering student. For my last exam I'm studyng the wind effects around a building using fluent. So, I have built the mesh grid in gambit but I have a problem. I am not sure which kind of bundary condition I have to put on the sky face and on the two side faces. I need to use symmetry condition or wall condition??

thanks for your help! RR

Fixed total pressure of zero. Pressure inlet with 0Pa gauge relative to operating pressure.
