  Molecular dynamics has been widely used to numerically solve equation of
motion of classical many-particle system. It can be used to simulate many
systems including biophysics, whose complexity level is determined by the
involved elements. Based on this method, a numerical model had been constructed
to mimic the behaviour of malaria-infected red blood cells within capillary
vessel. The model was governed by three forces namely Coulomb force, normal
force, and Stokes force. By utilizing two dimensional four-cells scheme,
theoretical observation was carried out to test its capability. Although the
parameters were chosen deliberately, all of the quantities were given arbitrary
value. Despite this fact, the results were quite satisfactory. Combined with
the previous results, it can be said that the proposed model were sufficient
enough to mimic the malaria-infected red blood cells motion within obstructed
capillary vessel.
