In order to confirm the fundamental issues of the multi-scale modeling and the procedure of coarse-graining in polymer simulations, the differences and similarities of several kinds of mesoscopic simulation methods, especially the coarse-graining particle dynamics and the dynamical density functional methods, were critically compared and analyzed based on our recent published works. We mainly discuss the fundamental differences of the description of coarse-graining procedure between the macroscopic and microscopic points of view. We conclude that though there still exists a wide gap between the methods, a critical comparison between the two will bring us a step towards quantitative multi-scale modeling.
