Command line arguments

The following command line options are supported:

Argument	Usage	Description
input_file -i input_file	mandatory	name of input file which holds all the parameters used for optimization
-o output_prefix	optional	The output_prefix will be the name of the generated airfoil as well as the subdirectory prefix for the intermediate data files for visualization
-a airfoil_file	optional	Name of airfoil file which will be used as the seed airfoil - overwrites airfoil_file in namelist &optimization_options of the input file
-r reynolds	optional	Default Reynolds number for operating points - overwrites re_default in namelist &operating_conditions of the input file
-h	optional	Shows command line help

If the output_prefix is omitted, the stem of the input file name will be taken as the ‘output prefix’.

Example:

xoptfoil2 -i JX-G3-100.inp will have the output_prefix JX-G3-100 and the name of the optimized airfoil will be JX-GT-100.dat.

The -a and -r arguments are useful for automation: a single input file can serve several optimization tasks by overriding airfoil or Reynolds number on the command line.

Put the command to run Xoptfoil2 in a batch file (shell script) so you can start the optimization with a double-click in Explorer.
