Regarding wall functions in SU2 v6.0 Falcon
For those who use the latest version of SU2,
In the new config template, there is a section for defining wall functions which wasn't there before: Code:
% Viscous wall markers for which wall functions must be applied. (NONE = no marker) I would like to ask if anyone uses this functionality and if they could share their experiences as to what kind of wall functions are implemented and how they are used. Thank you. |

Hi omdemircan,
I found a list of possible models in the SU2 doxygen documentation: NO_WALL_FUNCTION No wall function treatment, integration to the wall. Default behavior. STANDARD_WALL_FUNCTION Standard wall function. ADAPTIVE_WALL_FUNCTION Adaptive wall function. Formulation depends on y+. SCALABLE_WALL_FUNCTION Scalable wall function. EQUILIBRIUM_WALL_MODEL Equilibrium wall model for LES. NONEQUILIBRIUM_WALL_MODEL Non-equilibrium wall model for LES. |
Hi,
I am not sure however how mature the feature is. See https://github.com/su2code/SU2/pull/530 for more information. Without the mentioned V&V I personally wouldn't recommend to rely on the solutions (if it runs fine in the first place). If you want to get involved you are more than welcome to contribute, e.g. setting up simple Testcases. Cheers, Tobi |
Thanks, Tobi.
Yes, it appears these wall function options are just placeholders for now - when the job is executed the code reports "Wall function treatment not implemented yet". |
