Hello,

I'm trying to work with the Peng-Robinson equation of state and am getting a RuntimeError "Cubic root external functions are not available."

I went into the documentation to try and sort through it, and appears this error is in the documentation as well.

I believe the issue causing this error raised in the documentation is the same that raises it for my local problem - thus I'll lean on the documentation example rather than walking through my setup.

Thanks for any support!

Best,
Ian

ah - thanks for the quick response! That did it!

just for documentation for a future person checking this out, I ran idaes get-extensions (an 's' at the end of the command, was possibly a typo or perhaps a different version).

Thanks a lot for catching that, it was indeed a typo and the correct command is idaes get-extensions (I've edited my original post).
