If V 0 lies outside this range, the workflow rescales the volume to V 0 and repeats the fitting and analysis steps until V 0 is in range. As a fail-safe, the workflow terminates if an in-range V 0 cannot be determined after a set number of steps. A final NVT "production run" is then performed at volume V 0 with a quench temperature schedule to move the atoms into their lower-temperature disordered configuration. A few different options for the quench temperature schedule are available: a "slow" quench, which ramps down the temperature in NVT, and a "fast" quench, which performs a T = 0 DFT relaxation of the structure.
