March 18, 2021 at 8:56 amBibillSubscriberDear all,nI would like to use a hybrid RANS/LES model with realizable k-epsilon for the RANS model and Stress Blending (SBES) for the scale-resolving option.nIs it possible to specify the wall-function with a UDF or should we obligatorily use the scalable wall-function ?Thanks in advance!n
March 18, 2021 at 1:19 pmKarthik RAdministratorHello,nHave a look at the following macro and see if this helps? DEFINE_WALL_FUNCTIONSnBtw, just curious - why are you attempting to add your own wall function?nKarthiknn
March 18, 2021 at 2:01 pmBibillSubscriberThanks Karthik four your answer!nYes indeed it is the macro I have used to define my own wall-function and it works properly when solving RANS equations! However, what I was asking is how to manage to use this wall-function for a SBES scale-resolving option ?nIf you look at the picture, the only option that can be considered is Scalable Wall Functions and no more User-Defined Wall Functions...n
