We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

You may find some hints here   https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v242/en/flu_udf/flu_udf_ModelSpecificDEFINE.html%23flu_udf_sec_define_wall_functions     You may find y+ is only defined in the near wall cell, so also have a look at the adjacent cell/thread section of the manual.Â
