Lipid membranes exhibit a large spectrum of fascinating physical
behavior, spanning many orders of magnitude both in length- and time
scales. To cover this wide range, models of different resolution have
been developed, from atomistically resolved lipid representations to
triangulated fluid-elastic surfaces. In the intermediate regime of
about 100 nanometer length scale and micro- to millisecond time scale
mesoscopic coarse-grained models have recently covered much ground.
