Hello all,


I'm confused by the nomenclature used in Foam versions 2.3 and 5.0. What is the equivalent of muSgs from OpenFOAM version 2.3 in the 5.0 version? What is muSgs and what is its purpose?


Thank you for your help !!!

If I remember correctly, in earlier versions turbulent viscosity was specified separately -- with different names -- for various RANS models and LES models -- hence the nuSgs (refering to sub-grid turbulent viscosity). Now it has been generalized an is nut for all turbulence models. As for muSgs, that's simply the compressible counterpart of nuSgs.
