boudary layer distance in CFX POST
 

Hello I'm vac. I am modeling a simple duct flow problem and using SST model. Y+ value is below 1.0 and maybe node number in boudary layer is enough, but I want to decrease the node number. How can I know the boudary distance from wall in CFX POST? Thank you in advance.

You need to go back to your mesher and remesh.

You can plot the YPLUS variable in CFX-POST on the wall. This should give you a good idea of the first cell distance from the wall.
