How to deal with the divergence terms.....??I need to introduce a new term in the new turbulence model that I've been working on.
Mathematically it is written as:: D/Dt(k/omega) = div.(phi k/omega), { considering steady state and incompressible flow} Now I would define this as:: volScalarField DDTkw = fvc::div(phi_,k_/omega_); This DDTkw field will later be used in some other expressions. But we know that openFoam uses FVM to solve the RHS of this eqn. Which means, I will obtain, volScalarField DDTkw = "integral of div(phi,k/omega) dV" So my questions are:: 1) Is my concept correct?? Did I get it right until this point? If yes, my second question follows:: 2) The term that I require is only div(phi,k/omega) i.e. without the "integral......dV", How do I deal with this? Anybody with any idea in this regard?? Any heads up highly appreciated. Thnx. Nikesh |
