Dear CFX experts
As I know that we can adapt the mesh in CFX Pre. But I cant find the Y+ in the variable list? Any body has idea how to get the mesh adaptation based on the Y+.
Thank in advance
I'll have to check on this tomorrow, but I believe y+ is only calculated at walls. If that's the case it is not a volumetric variable and cannot therefore be used as a mesh adaption criteria.
BUT... you could create an algebraic additional variable that calculates y+ manually, and then use this variable to adapt your mesh.
That being said, if what you're trying to do is to automatically refine your mesh based on y+, what you should do instead is manually generate a few meshes with decreasing y+ and compare their results. I don't think using mesh adaption is the correct approach in here, since you won't get a nice, smooth and gradually increasing mesh spacing near the wall by using mesh adaption.
actually my mesh has y+ less two every where except at the leading edge. where it goes to 6 in very thin region. I need to determine the effect of this on my results
