4.4.3. Command Line Argument Options

Table 4.7: Command Line Argument Options for Chemkin Pre-processors and Program Executables provides a list of the available command-line argument flags for each of the Ansys Chemkin Pre-processor components and program executables. Table 4.7: Command Line Argument Options for Chemkin Pre-processors and Program Executables also indicates whether each of the input or output files is required and which programs use them.

For optional files, default file names are provided if files are not specified on the command line. These default file names are listed in Table 4.7: Command Line Argument Options for Chemkin Pre-processors and Program Executables. The command-line arguments allow specification of full pathnames to input and output files, in addition to the file names themselves. By default, any unspecified path is assumed to be the local working directory. Examples of using the command-line arguments are provided in Running A Sample Step by Step.
