The computational cost and effort of this procedure can be dramatically simplified if one is simply interested in generating polymer morphologies for pedagogical purposes (as opposed to probing specific intermolecular interactions), in which case, doing atomistic simulations may not be necessary and a more coarse picture could suffice. In this situation, the user can directly download the desired all-atom replacement of the CG model structures that are generated interactively by CHARMM-GUI or perform a quick force field optimization (also feasible interactively using Avogadro), and render them without the need for running dynamical simulations on a local computer or a computational cluster.
