Yes, I agree with you.

>It changes rapidly or is doesnt change that much?

I found out that:

If the viscosity is high, the pressure field will change dramatically
due to the external disturbance. Like my case, my unbalanced force is
not low enough, so the first iteration gives pressure varies from 0-100
while the pressure of some pore is about -10000 in the second.

If the viscosity is low, the pressure field won't change much between
the the first iteration and the second iteration. I think it's because I
increase the value of the elements in the conductivity matrix G,
therefore influence of the velocity of the particles is reduced.

GP=Ev+Qq+Qp

>changing viscosity is the same as changing permeability in the code

Thanks for the information. I didn't know this before.
