In LES, filtering the navier-stokes equations generates a sub-grid stress term which can be written as the divergence of a tensor R. The SGS turbulence model provides this. The use of the term divRhoR is supposed to reflect the fact that this is div(rho*R); in reality its just a function call to provide the correct field
