There are several special characters that you can include in a filename. Using one of these character strings in your filename provides a shortcut for numbering the files based on various parameters (i.e., iteration number, time step, or total number of files saved so far), because you need not enter a new filename each time you save a file. (See also Section 4.3.4 for information about saving and numbering case and data files automatically.)
%tin the file name. For example, you can specify
contours-%t.psfor the file name, and the solver saves a file with the appropriate name (e.g., contours-0001.ps if the solution is at the first time step).
This automatic saving of files with the time step should not be used for steady-state cases, since the time step will always remain zero.
%fin the file name. The usage is similar to
%t. For example, when you specify
filename-%f.psfor the file name, the solver will save a file with the appropriate name (e.g., filename-005.000000.ps for a solution at a flow-time of 5 seconds). By default, the flow-time that is included in the file name will have a field width of 10 and 6 decimal places. To modify this format, use the character string
yare the preferred field width and number of decimal places, respectively. FLUENT will automatically add zeros to the beginning of the flow-time to achieve the prescribed field width. To eliminate these zeros and left align the flow-time, use the character string
This automatic saving of files with flow-time should not be used for steady-state cases, since the flow-time will always remain zero.
%iin the file name. For example, you can specify
contours-%i.psfor the file name, and the solver saves a file with the appropriate name (e.g., contours-0010.ps if the solution is at the 10th iteration).
%nin the file name.
This option can be used only for hardcopy files.
The default field width for
%n formats is 4. You can change the field width by using
%xn in the filename, where
x is the preferred field width.
