p3vd New Member Join Date: Jan 2012 Posts: 2 Rep Power: 0	Hi All, I am working on my research project " prediction of wind loads on house roof during hurricance" where I have designed a house structure with 8 feet y-direction, 30 feet x-direction, 20 feet z-direction with roof socket of 2 inch and upstream, downstream set as 10 times volume of the geometry of house. I am confuse about setting the boundary conditions. I have taken velocity inlet and pressure outlet with house as wall but am confuse about the region between velocity inlet and wall of the house and from wall of the house to the pressure outlet, Can I take as outflow boundary condition for rest of the part?
