How to remove Wall Function for k-omega SST Model?
I am doing a 2D bluff body simulation. My first boundary layer is quite fine (0.5 mm [about D/200]) and the y+ value comes between 4 to 10. I want to remove the default wall function from the k-w SST model. I couldn't find any option in the Graphical User Interface (GUI) of Fluent to disable the Wall Function.
I found the following command online that is said to turn-off the wall function for k-w SST but couldn't find any proper reference or document to verify it:
(rpsetvar 'kw-set-wall-w? #t)
I have a few follow up questions. I would be grateful if you could answer even one or few of them. Thanks.
- Is it possible to remove wall functions from k-w SST model from GUI?
- Are there any documents or references to understand how (rpsetvar 'kw-set-wall-w? #t) works (I want to understand if it removes all wall functions for k-w SST model or only removes for a few parameters like k or w)
- What is the default wall function used by k-w SST model?
Any insight would be greatly appreciated.
