### 13.2.1. Running Vista TF from the Command Line

You can run Vista TF from the command line of your operating system. By default, the executable will look in the current directory for the required input files for your case. One of the input files, which has a default name of `vista_tf.fil`, contains the names of the other input files that are to be used for the case. If this input file has a different name, specify that name as the first command line argument. For example:

`VistaTF.exe myfile.fil`

When the executable runs, it writes text output messages to the console. To redirect these messages to a file, append `-silent` to the command line. The default file name for storing the redirected output messages is `screen.scn`. To store the output messages in a file of a different name, specify that name following `-silent`.

After running the program, several files are produced in `.csv` format as the basis for producing plots with CFD-Post or in `.txt` format as the basis for producing plots with Tecplot.

The input and output files for `VistaTF.exe` are described in detail in Input and Output Data Files for Vista TF.
