Hi,
I want to simulate a non-Newtonian fluid flow by using interFoam solver.
I modified the transportProperties as follows:
Code:
water
{
    transportModel  poweLaw;
    nu              nu [ 0 2 -1 0 0 0 0 ] 0.001;
    rho             rho [ 1 -3 0 0 0 0 0 ] 1000;
    powerLawCoeffs
    {
        k               k [0 2 -1 0 0 0 0] 100;
        n               n [0 0 0 0 0 0 0] 0.1;
        nuMin         nuMin [0 2 -1 0 0 0 0] 1;
        nuMax        nuMax [0 2 -1 0 0 0 0] 10000;
    }
}
And I run it. It seems that everything is fine.
But the result of alpha.* is keeping the initial state. In other words, the fluid does not flow. And other results (U/P) are also not correct.
I modify the water transportModel to Newtonian, and run it again.
Everything is fine.

Maybe this problem is infantile, but as a beginner I still don't know where is wrong. Any help is greatly appreciated.
Thanks!

Yongxiao
