Porous domain vs Subdomain General Momentum Source

November 18, 2008, 16:37

Dear All, I have find an interesting fact. If I set Darcy equation Source = -(Viscosity/Permeability)*Velocity/Porosity as a General Momentum Source, the results I obtained are not logical and very different from porous domain with the same data. Does anyone have a comment on this? Alvio

Hi, the differences in the results were due to the fact that I was using Velocity in standard frame instead of simply the velocity (I have relative motion between the domains)
