The postprocessing files created by IBIS are placed in directories that are specified in the IBIS program. Generally, two directories are created, one for the color graphics files, and another for the raw data that is used for line graphics. We will return again to the familiar balloon example to illustrate the files and their naming conventions. The balloon example contains the following three lines in the IBIS program
grid 7 0.000165 500 ... visual -h 128 -w 256 -n 5 -d 8 -p binary -b balloon graphics -n 50 -p line -b balloon
The line starting with visual specifies the color file directory binary and the file basename balloon. The second line specifies the line file directory line and the file basename balloon.
Upon completion of IBIS, the binary directory will contain 101 datafiles because the program takes 500 timesteps, and outputs a color plot file every 5 steps. These files will be named
balloon.0000 balloon.0001 balloon.0002 balloon.0003 ... balloon.0100
The line directory will contain 550 datafiles because the program takes 500 timesteps, and outputs five line plot files every 50 steps. These files will be named
balloon.h.0000 balloon.i.0000 balloon.l.0000 balloon.s.0000 balloon.v.0000 balloon.h.0001 balloon.i.0001 balloon.l.0001 balloon.s.0001 balloon.v.0001 balloon.h.0002 balloon.i.0002 balloon.l.0002 balloon.s.0002 balloon.v.0002 ... balloon.h.0010 balloon.i.0010 balloon.l.0010 balloon.s.0010 balloon.v.0010
The postprocessing files can also be edited and used in other applications. However, because they are the results of a calculation, manually changing them is not recommended.
In the following pages, the file structure of the postprocessing files are described.
