Hi, I want to know if anybo
 
Hi,

I want to know if anybody had alredy use turbFoam with a high value of nu.
I use BirdCarreau.
I note that, with n=1, and nu0<e-3 (let nuInf=0, k=1000), I can make a computation.
But when I put n=0.14, nu0=e+12, the computation goes off! even if I put a very very low deltaT (=e-7)

I have already use a first solution done by an other solver (simpleFoam) to have a solution with respecting the mass continuity (divU=0) and after that I put it in intial field for the computation in turbFOam. But this method did not work too.

Hope that anybody will give me a hand,

Lam
