Hi everyone,
I am student and I have really small experience on CFD.
For my master thesis I'd like to compare results from SST-DDES and SAS-SST for a flow around a cylinder with RE = 3900.

While I could find plenty of documentation for setting up the DDES case I had troubles for the SAS.
Can anyone help me out about the boundary conditions I should pick for k,nuT,omega,p and U?
Are there any particular details I should care of?
Any help/suggestion will be highly appreciated and rewarded with a big smile


EDIT:
From what I understood since SAS can be considered an unsteady RANS method I shall use the same boundaries I would use on k-omega SST.

Despite that I think I should set different values for k, omega and nut at the inlet but I haven't understood which formulas i couldI can't find anywhere how to set those values use.
Can please anyone help me?
