stressComponents utility in LES calculations
Hi everybody,
I'm working on a 2d LES simulation on a channel flow. The model I use is the oneEqEddy, with the same settings of the pitzDaily LES pisoFoam tutorial. So, the matter I wish to investigate is about the meaning of the stressComponents utility output in a case such this: are these components referred to the Smagorinski stress tensor (TAUsgs)? If they not, what actually do they represent in a LES simulation?

Thank you in advance

Any replies?

In its source code, stressComponents is defined as:*2*dev(symm(fvc::grad(U)))

I think it's not related to sgs stresses, its the deviatoric stress components.
