How is free energy calculated in Lammps?

One way to calculate the free energy profile is to extract the partition function from a classic (unbiased) molecular dynamics simulation, and then to estimate the Gibbs free energy using Δ G = − R T ln ⁡ where is the free energy difference, the gas constant, the temperature, and the partition function.

Can LAMMPS read XYZ file?

The molfile format supports reading data through using the VMD molfile plugin interface. The style value determines the file format to be used and can be any format that the molfile plugins support, such as DCD or XYZ. Note that DCD dump files can be written by LAMMPS via the dump dcd command.

How do I create a dump file in LAMMPS?

To write gzipped dump files, you must either compile LAMMPS with the -DLAMMPS_GZIP option or use the styles from the COMPRESS package. See the Build settings page for details. The atom/gz, cfg/gz, custom/gz, and xyz/gz styles are part of the COMPRESS package. They are only enabled if LAMMPS was built with that package.
