Abstract

Modelling lipid membranes is particularly challenging because many of the bilayer properties arise from the concerted action of many molecules on the mesoscale, requiring large simulation cells and long times of at least milliseconds. This makes coarse-grained methodologies particularly attractive for simulating lipids. This chapter reviews the main current strategies for coarse grained modelling of lipid systems. Coarse graining is introduced on several length scales, allowing access to different aspects of processes unfolding at lipid interfaces and within the bilayer.
