This analyzer periodically writes the w-field configuration to frames of a trajectory file. The resulting file can be read and postprocessed using the ANALYZE command of pscf_pc or pscf_pg.

Parameter File

The parameter file format for the associated block is shown below:

TrajectoryWriter{
  interval           int
  outputFileName     string
}

Both parameters are required. The interval must be positive Meanings of the parameters are described briefly below:

Label	Description
interval	number of steps between data samples
outputFileName	name of output file

Output

During the simulation, the w-field configuration is output to file {outputFileName} every interval simulation steps.

The resulting file contains a header section followed by a sequence of frames. The format of the header is the same as that used for an r-grid field file, and each frame uses the same format as that used for the data section of an r-grid field file.
