This analyzer periodically writes the composition configuration for each component to file. The output is analogous to that of a trajectory filed produced by the TrajectoryWriter analyzer, except that it outputs frames containing monomer concentration (or volume fraction) fields (c-fields) for all monomer types at regular intervals, rather than monomer chemical potential fields (w-fields).

Parameter file

The full parameter file format is shown below:

ConcentrationWriter{
  interval*          int     (1 by default)
  outputFileName     string
}

Meanings of the parameters are described briefly below:

Label	Description
interval*	number of steps between c-field configurations output to file
outputFileName	name of output file

Output

During the simulation, frames containing the monomer concentration fields (i.e., c-fields) for all monomer types are output to the file named outputFileName every interval simulation steps. The format of the resulting file is analogous to that of a w-field trajectory file: It contains a header with the same format as that used for the header of an r-grid field file, following by a sequence frames, in which each frame uses the same format as the data section of an r-grid field file.
