"In those pieces of apparatus [computing machines] I see not only devices to make the forces of nature serviceable in new ways, no, I view them with much greater respect; I dare say that I see in them the true devices for unveiling the essence of things"
Ludwig Eduard Boltzmann [1]

Computer simulations are used to obtain quantitative results, under various thermodynamic conditions, for realistic models which are parametrised to study a specific atomic or molecular system with a certain degree of realism, or force fields, which consist of transferable parameters for molecular sub-units, usually at the atomistic level. Force fields are designed to be applicable to a variety of molecular systems, in particular for flexible molecules. Computer simulations are also used to perform "computer experiments" on idealised models in order to test theories with a view to arriving at a better understanding of the underlying physics of a system.

The two predominant computer simulation techniques used in the study of soft condensed matter are:
