Differences in Formulation for devRhoReff and divDevRhoReff

Hello everybody,
I'm using the compressible k-Epsilon turbulence model and I've got a question about the formulation of the total stress term devRhoReff and the source term for the momentum equation divDevRhoReff. The former is defined as Code:
-muEff()*dev(twoSymm(fvc::grad(U_))) Code:
- fvm::laplacian(muEff(), U) - fvc::div(muEff()*dev2(fvc::grad(U)().T())) Code:
fvc::div( -muEff()*dev(twoSymm(fvc::grad(U_))) ) Can someone explain this behaviour to me? Are my assumptions not correct? Thanks a lot martin |
