<br/>Fast Lubrication Dynamics (FLD) approximation was used to simulate suspensions of hard spheres in a Newtonian fluid.  Several revisions were made to FLD to compare with literature results and was then used to calculate the relative viscosity of the suspensions to verify the results.  The relative viscosity values determined matched the accurate results of Stokesian Dynamics.  In a suspension of particles, the motion of each particle is transmitted through the suspending fluid making the long-range interactions of the particles important, especially in the dilute case.  When particles are close together, the short-range interactions dominate.  FLD includes both long- and short-range interactions while improving simulation efficiencies over Stokesian Dynamics.<br/>
