  A brief review is presented of the scaling of complex fluids, polymers and
polyelectrolytes in solution and in confined geometry, in thermodynamical,
structural and rheology properties using equilibrium and nonequilibrium
dissipative particle dynamics simulations. All simulations were carried out on
high performance computational facilities using parallelized algorithms, solved
on computers using both central and graphical processing units. The scaling
approach is shown to be a unifying axis around which general trends and basic
knowledge can be gained, illustrated through a series of case studies.
