SMS:PTM Control File

The PTM program control file (.pcf) contains run time instruction for the model.

File Overview

The program control file (PCF) contains all the information necessary for the PTM to perform the simulation requested. The PCF file is a keyword oriented file. Lines in the file should contain either comments, with the line beginning with a "#" symbol, or a keyword, a single word beginning with a colon, ":", and its associated values. Some keywords have no associated values, e.g.:

   :MOBILITY_MAPPING

These are generally on/off instructions to the model. Keywords pointing ot filenames or setting constants have one or two associated values, e.g.:

   :MESH_FORMAT ADCIRC
   :MESH_FILE estuary.grd

Keywords and values are not case sensitive with the single exception of the simulation output file names (i.e. file names like "Run_C1_Tp_12s_paths.out" are possible).

The PCF file is read until the instruction :

   :END_DATA

is encountered.

The following list summarizes the rules for construction of a PCF:

• Keywords should be preceeded with ":".
• Comments should be preceeded with "#".
• Keywords are not case sensitive.
• Keywords and value(s) are white space delimited (tab or space) and, so, should not contain blanks.
• Keywords may be placed in any order in the file.
• If a keyword appears more than once, then the final incidence is used.
• All value units are S.I.
• All times are relative to the clock defined by the currents file.
