Hi Foamers turbulence->div
 

Hi Foamers

turbulence->divRhoR(U) ,

can any of you explain me what this line does (found in coodles:: UEqn.H)

Thanks a lot

In LES, filtering the navier-s
 

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
