DL_MULTI requires five input files named CONTROL, CONFIG, FIELD, TABLE and REVOLD. The first three files are mandatory, while TABLE is used only to input certain kinds of pair potential, and is not always required. REVOLD is required only if the job represents a continuation of a previous job. TABLE and REVOLD are the same in DL_MULTI as in DL_POLY_2 and are not described further here. In the following sections we describe the changes to the standard DL_POLY_2 files.
