What is Molecular Simulation? ¡ Molecular simulation is a computational “experiment” conducted on a molecular model. ¡ Many configurations are generated, and averages taken to yield the “measurements.” One of two methods is used: Molecular dynamics Monte Carlo Integration of equations of motion Ensemble average

Apr 29, 2013 · • Molecular modelling or more generally computational chemistry is the scientific field of simulation of molecular systems. • Basically in the computational chemistry , the free energy of the system can be used to assess many interesting aspects of the system.

more quickly in simulation, or making the simulation reach all low-energy conformational states more quickly. – For example, one might apply artificial forces to pull a drug molecule off a protein, or push the simulation away from states it has already visited. – Each of these methods is effective in certain specific cases. 34
