log-law change - Fluent
I want change the log-law function in Fluent...
I changed it, considering the strategy present in the manuals of fluent, by creating an UDF where I give the new expressions for UPLUS_TRB, DUPLUS_TRB and D2UPLUS_TRB. But, someone told me that I need also change the viscosity. But I don't know how I do that. Please, someone can help me? Where I can find information about this? If I just change the Uplus expression as a function of Yplus, is that correct.
Another thing... how I can see/get the values of Uplus to represent it as a function of Yplus? To check what Fluent is assuming.
Anyone can help me?
