Creeping Flow

Hello!
I am trying to simulate the creep flow in order to calculate darcy's coefficient for a periodic array of sphere. I performed a mesh refinement study. Still the equation does not seems to satisfy completely despite of convergence. Since I am using 4.3b version of Comsol I do not have predefined model for creeping flow. So what I did is that I add convective term in the volume force (attached). Just to cancel the effect due to convection which indeed is negligible.
However, despite of using extremely fine mesh. My continuity and navier stokes equation does not satisfies very well.
Thank you!
Ayush
