Airfoil Analysis Module: graphs
Hi,
I start with the questions, and provide the context of my use of QBlade afterwards.
- I run the airfoil analysis (tried both with an imported one and from the ‘SampleProjects’) and cannot see the graphs for Cm and Cl/Cd (see attached ‘MyAnalysis’). I played around with the options found when right-clicking on the figures.
- I saw in the manual that also the pressure coefficient can be visualised (see ‘FromManual’), but I didn’t find the way to do that.
My name is Tania Bracchi, I am associate professor at NTNU, Trondheim. I am preparing the assignments for my students in the course “Design of a Wind Turbine” for next academic year.
I just started using QBlade, and I must say it has a quite intuitive user interface. Thank you for the great work, and I truly appreciate the free academic license.
Kind regards,
Tania

Hi Tania,
thanks for the nice introduction.
It seems to me that you are doing things in the correct way. The Cm and Cl/Cd data should be available. My guess is that the graphs could be set to the wrong graph type. Try right clicking a graph to check what graph type is selected, the graph type is shown at the very bottom of the context menu that pops up. If you change the graph type to “Polar Graph” you should be able to display Cm and Cl/Cd. You can change the currently plotted variable by double clicking on a graph and selecting the variables for the x- and y-axis.

Dear David,
Thank you so much for the fast answer.
I did solve it by double clicking on the graphs, as you suggested. It seems that different graphs allow different selection; f.ex. the Cm is visible if I substitute the Cl-alpha with Cm-alpha (this info in case someone else encounters the problem).
Looking forward to explore more!
Kind regards,
Tania
