The need for mesoscopic methods
Mesoscopic Simulation of Polymers

At the microscopic level, both quantum and atomistic methods are used. We refer the interested reader to the article on atomistic polymer simulation [AF 6 042] . Static properties are obtained by solving the time-independent Schrödinger equation, while dynamic properties are calculated by solving Newton's equation. On a macroscopic scale, the Langevin or Navier-Stokes equations are used to account for continuum mechanics. Between the two levels of representation lie mesoscopic methods, usually situated between 10 nm (10 ^...
