Hi:

I am running icoFoam. However, wanted to compute the turbulent variable 'nuSGS' without using the turbulence model. I tried to compute the following way:

surfaceScalarField nusgs = sqrt(mesh().V()/thickness)*symm(grad(U));

computing the thickness variable as given in LESdeltas, but was not able to work it out.

some errors include:

error: no match for call to (Foam :: fvMesh) ()
error: grad was not declared in this scope..

Can someone elaborate on how to obtain this quantity?

further, in the incompressible code, Can i Add this computed field to constant "nu" to make it an effective nueff = nu+nusgs.


Thanks,

Vatant
