In this simulation butane molecules in gas phase is considered. This is a very simple example for demonstrating music MD. The butane molecules are modeled using the united atom model with methyl and methylene groups. Molecules interact with each other through Lennard Jones interactions. There are intramolecular potentials for bond stretching, bond bending and bond torsion. The post code analysis is used to get diffusivities energy averages etc.
