Finally I got something running, which seems to be right... Would somebody be so kind and try to verify my solution for the problem? Just because I'm not quite sure about it...


volTensorField gradV = fvc::grad(V);
volTensorField gradVT = gradV.T();
volVectorField problemTerm = U & (gradV + gradVT);

fvVectorMatrix VEqn
(
...
- fvm::laplacian(nu, V)
- problemTerm
);

...

solve(VEqn == - fvc::grad(p))



Thanks!
Stefan
