CMS-Flow Output files

ASCII Output Files

ASCII Output files from CMS are in the form of three different files listed below. These file types were chosen because they are supported in SMS and can be read in directly.

• SUPER (*.sup) files - hold the filename information for other supporting files.
• 2D Scatter Point (*.xy) files - hold the geometry information for the records located in the various .DAT files.
• ASCII Dataset (*.dat) files - hold the data records written at the selected output times.

SUPER file description

(Adapted for CMS from the SMS Wiki) Super files can still be opened in SMS. These contain a 2D scatter point file and the corresponding ASCII CMS Solution data file.

If a super file is selected using the File | Open command, each of the files listed in the super file are opened and imported. This makes it possible to quickly read in several files without having to identify each file individually in the file browser.

A sample of the file format for a super file is shown below. The first line in the file is the SUPER card, which identifies the file as a super file. Each of the other cards shown are optional. Each of the file cards has a card identifier representing the type of file. The identifier is followed by a file name. The file name should be a complete path if the file is not in the same directory as the super file. Any suffix may be used for the file name.

SUPER	/* File type identifier */
SCAT2D filename	/* 2D scatter point file */
DATA filename	/* Dataset File */
...	/* repeated DATA lines as needed */
DATA filename	/* Dataset File */

SUPER
SCAT2D	"Phase2.xy"
DATA    "Phase2_eta.dat"
DATA    "Phase2_vel.dat"

2D Scatter Point Files (*.xy)

(Adapted for CMS from the SMS Wiki) Two-dimensional scatter point sets are stored in 2D scatter point files. The file includes the scatter point locations and requires that functional information be defined in a separate dataset file. An XY coordinate pair defines each point in a scatter point set. The format allows time variant datasets to be associated with scattered data points as well as to organize datasets by allowing the user to assign an ID to the scattered dataset.

The super file saves and references the scatter and dataset files.
