3D unconfined sphere in stokes regime
 

Hi dears I have been stucked extremely in the proper simulation of stokes flow (Re<1) past an unconfined sphere using FLUENT. The total drag coefficient is computed about 35% greater than the analytic and experimental data. Is there any one who has the related case and data file to send me Thanks in advance
