How to define Darcy law in porousZones
 
Hello,

If I have only a simple Darcy's law grad(p)=-mu/k * U,
k - permeability [m^2]
mu - viscosity [Pa*s]

how should I define it in file porousZones? Is it like this: d=1/k and f=0, or no? e.g.
Code:

        Darcy
        {
            d  d [0 -2 0 0 0 0 0] (1e15 1e15 1e15);
            f  f [0 -1 0 0 0 0 0] (0 0 0);
        }
