 hi,
   i have just finished my Masters in chemistry and wish to take up computational
 chem. for research. i need little clarification in this regard. can someone
 explain the difference ( if any) between "molecular modelling" and
 "molecular simulation" . as far as i know "molecular
 simulation" is generally associated with liquids and gases but
 "molecular modelling" is associated with proteins organic molecules
 etc. can anyone explain their differences ( in terms of what one does during
 research in these areas). how are these two different in terms of application to
 industry? For example, is molecular dynamics/simulation applicable to drug
 design?
 regards,
