Hi everyone,

I am implementing kOmegaSSTSAS turbulence model (using pimpleFoam solver) to simulate the flow around a cube for relatively high Re (between 10^4 and 10^7).

As far as I know, there are no tutorials using this specific turbulence model. I have noticed that kOmegaSSTSAS is derived from kOmegaSST. The only additional parameter required is "Delta" or "LES Delta".

I have read through the extended guide but I cannot understand the physical meaning of this parameter. Also, there are many different ways to specify Delta (https://www.openfoam.com/documentati...1LESdelta.html) and I don't know which one would be more appropriate for the kOmegaSSTSAS.

So far I have tried the "cubeRootVol" definition as suggested in https://develop.openfoam.com/Develop...kOmegaSSTSAS.H , but I am not sure if this is correct.

Could anyone help me with this?

Thanks in advance!
