understanding kEpsilon model source code
Hi,
I have a question about the implementation of the kEpsilon source code in the file kEpsilon.C (.../src/turbulenceModels/incompressible/RAS/kEpsilon). In line 181 the divDevReff()function is declared. Can anybody explain the code in line 185 and 186 to me? Thanks! 
Can you post that lines out?

Hi, I don't understand the following lines:
return ( laplacian(nuEff(), U) div(nuEff()*dev(grad(U)().T())) ); The whole expression is defined as divDevReff() and should return the source term for the momentum equation. I tried to write it down mathematically but I failed! Thanks for your help! 
Some people don't know that dev() is a transposition!
Well  at least it was me who doesn't know until I was told. But what is this T() ? 
Hmm, are you sure that dev() is a transposition? I think that .T() is a transposition and dev() ist the deviatoric component ( tensor 1/3*(trace tensor)*I ) of the tensor grad(U)().T()?
But I wonder if dev() shouldn't be dev2()? 
Actually your statement makes more sense.
I haven't thought about the fact that grad(U) is a tensor and not a vector like U itself!
