DESCRIPTION:Coarse-grained models for liquid crystals are typically based 
 on pair potentials where an entire mesogenic molecule is represented by on
 e (or a few) anisotropic geometrical object (e.g. a spherocylinder\, or an
  ellipsoid) with either purely repulsive or attractive-repulsive interacti
 ons. Computer simulations relying on these simple off-lattice models are a
 ble to reproduce the experimental phase sequences and order parameters of 
 thermotropic mesogens and are useful for studying the relationship between
  specific molecular properties (e.g. shape or interaction anisotropies) an
 d macroscopic liquid crystalline behaviour.\n\nWe will review the principa
 l coarse-grained level models currently used in computer simulations of li
 quid crystals and discuss their advantages and shortcomings using the resu
 lts for selected cases.\n
