Simulation of fibers suspended in a liquid

A total number of 200 fibers are suspended in a liquid governed by the Stokes equations; due to gravity they fall downwards. The system is here simulated with periodic boundaries in all directions so that the total flow becomes that of an 'infinite volume'. Note the increasing concentration in the middle of the box.

The dimensions of the box is 20-by-20-by-40 units and each fiber is 2 units long.

Does the flow look different if you only suspend 100 fibers?
