[Workbench] Boundary Layer mesh on airfoil by CFX

mamly · August 29, 2015, 13:52

Hello friends
I am trying to mesh an airfoil by CFX workbench. As you know boundary layer is so important for airfoils.
But I dont know how can I generate boundary layer by workbench, is anybody familiar with that?
And can you send me a tutorial or an example?
Thanks guys

there are many methods to do this. You can use inflation to get the good boundary layer mesh

Why don't you check out the tutorials provided by ANSYS first?

Are you planning on a steady-state or transient calculation?

One approach could be to use inflation (also called prism layers) as Far suggested and then start with the SST turbulence model.

You should check what y+ numbers you need depending on the turbulence model you want to use.
