Wall function
 

Hello, All:

Can I use user-defined wall function instead of the default one in CFX-4 environment.

Thanks for any suggestions!

Hello, Thanks.

Do you have any experience to modify wall function to hold the rotationg wall.

Actually, I want to export y+ value from a CFD somution for a rotating wall.

Any suggestion?

Actually, I don't have experience in that field.

Do you need it for post processing or during the simulation? Where do you want to export it to?

I need to export it for mass transfer coefficient and I guess I should use a correct version of wall function as well as a correct definition of y+ on rotating plat
