Invoking Nalu-Wind - Command-line options

Nalu-Wind’s runtime behavior can be controlled by using several command line input options during invocation. Users can invoke -h to determine the various options available.

-h, --help

Print the help message describing all Nalu-Wind options and exit

-i, --input-deck

Use the filename provided as the input file. If this option is not provided, naluX will attempt to load a file called nalu.i in the current working directory as the input file.

-o, --log-file

The log file where the output generated by Nalu-Wind is directed to. If no file is provided, then naluX will use the base name of the Nalu-Wind input file with the extension .log as the output file. For example, if naluX was invoked as naluX -i ABL.neutral.i then the output will be redirected to a file named ABL.neutral.log. Note that the file is overwritten if it already exists.

-v, --version

Print the Nalu-Wind version string.

-p, --pprint

Enable parallel printing from all MPI ranks.

-D, --debug

Enable verbose debug printing to log file.
