Field Files

Command Files (Prev)         Self-Consistent Field Theory (Next)

Among the commands that can be issued from the command file for any PSCF program are several commands to read and write files that specify local concentrations or volume fractions of different types of monomer (referred to as "c fields") or corresponding monomer chemical potential fields (referred to as "w" fields).

Every PSCF program can read and write w and c fields using one or more file formats designed for field files. Each program uses the same file format or formats for w and c fields. In each such file format, a single file contains a description of the w or c fields associated with all of the different types of monomer present in a system.

Different field file formats are used by different programs. The r1d program for one-dimensional problems uses a simple format that lists values of fields on the nodes of a one-dimensional grid. The pscf_rpc and pscf_rpg programs, which both treat periodic structures, use the same set of three different formats to describe periodic fields. File formats used by different programs are described in more detail in several of the sub-pages linked below.
