How to display the list of command line arguments for OpenFAST executable?

Wind & Water Computer-Aided Engineering Software Tools

Hello,

On Windows, When I run:

openfast /h

I expect the program to print the list of all the command line arguments that can be specified. However, OpenFAST, doesn’t list any options:

 .\openfast_x64-v3.5.3.exe /h

 Syntax is:

    OpenFAST [/h] <InputFile>

 where:

    /h generates this help message.
    <InputFile> is the name of the required primary input file.

 Note: values enclosed in square brackets [] are optional. Do not enter the brackets.


 OpenFAST terminated normally.

The only option shown is the /h . How do I list all the options accepted by OpenFAST executable?

Best regards

Dear @Yoor.Thiziri,

/h is the only argument that is specifiable through the OpenFAST executable other than the name of the primary (.fst) input file. All input parameters to OpenFAST are set through its input files.

Dear @Jason.Jonkman,
Thank you for your answer. If I remember correctly, OpenFAST accepts also this option -VTKLin? is that different?

Thank you
Best regards,

Dear @Yoor.Thiziri,

Good point.

I forgot that there are a few other optional arguments, depending on the analysis you are doing. Unfortunately, it doesn’t look like these where ever added to the /h help menu. The optional arguments are:

  • h to display help
  • v to display the version number
  • restart to restart from a checkpoint file
  • vtklin to export vtk-based mode shapes after a linearization analysis
  • steadystate to use the steady-state solver to generate aerodynamic maps

Best regards,
