Environment variable problem

random_username · August 10, 2014, 13:33

I am having a problem that is most likely due to a basic mistake from my side, but I would really appreciate some help.

After installing SU2 I have added the environment variables to both system variables and user variables according to http://adl-public.stanford.edu/docs/...s+Installation. The variable is SU2_RUN and the Value is C:\SU2, which is the folder where all of my installation files are placed (no subfolders).

When in the in Console and typing SU2_CFD inv_NACA0012.cfg I get the error "SU2_CFD is not recognized as an internal or external command, operable program or batch file."

Obviously I am missing something, and I have searched these folums and google trying to figure out what, but to no avail. Can anyone help me out?

EDIT: Added C:\SU2 to the Path variable in environments as well and it works. Thanks, other thread.

I have met with the same problem. I guess maybe the computer cannot recognize what "SU2_CFD" is. Because the environment variable is named as SU2_RUN, and the executable path is also different from the .cfg file. The problem is how to use the executable command (SU2_CFD) to operate the .cfg and mesh files in another path. Hope for advice!

Please try compile source code on Linux or MacOS if you have these OS, this solve your problem greatly.
