Good morning,

I have a question regarding the python API. I am trying to incorporate a VSPAERO analysis in my code and I am trying to run a Steady Analysis to get the aerodynamic coefficient for a specific flight condition but I can't find it in the API. I can run the Sweep analysis and get my Cd or Cl but not the aerodynamic coefficient and I don't know how to proceed I didn't find it on the internet.

Thanks in advance,
Have a good day,

Simon

What aerodynamic coefficient do you want -- that is not the cl and cd?

Perhaps you mean pressure coefficient Cp?

You should be able to access Cp along a slice through the API.  It will be reported in some sort of Slicer results.

The full surface Cp's visible in vspviewer are not available through the API.

Rob
