Basics of modeling of molecules (and other many-particle systems) by means of classical statistical mechanics, from force field construction to molecular dynamics and Monte Carlo simulations. Emphasis is on the methodology of a computer experiment (pseudoexperiment). A simulation project is required, either developing a code for a simple system or using a simulation package. Edu-software is available.

Last update: Kolafa Jiří prof. RNDr. CSc. (17.09.2015)

Students will understand the principles of molecular modeling and simulation in the frame of quantum and classical thermodynamics. They will master MC and MD simulation methods including determination of various quantities. The students will be able to devise a computer experiment.
