Hello Everyone.
I don't know if this is the correct place to post my thread. I'm trying to simulate the flow in an air supply system (using incompressible S-A DDES) as you can see in the attached photo and I'm interested only in the flow in the duct's end region, but I'm noticing an odd behavior, the semi-spherical surface should be an outlet but the flow is not completely exiting throw the outlet, and I think that could effect the solution quality. My BC at the outlet: For U: Code:
outlet { type inletOutlet; value $internalField; inletValue $internalField; } Code:
outlet { type outletInlet; outletValue uniform 0; value uniform 0; } If this is wrong ... what I should use? Or I should use different outlet shape for my simulation? Thanks in advance. |
