Data Exports of Steady BEM Simulations
Hello everyone,
im using the steady BEM functionality. I conducted a simulation with “pitch controll” to match a desired power level over varyng wind speeds. Im especially interested in the resulting pitch angles. Is there a possibility to extract this data from the simulation?
Many thanks in advance!
Hi,
you can export the currently displayed values from any graph by hovering over the graph and right-clicking:
– Copy Data to Clipboard: Copies the numeric data of all curves to the clipboard.
– Export Graph to File: Saves the plotted data in a text file.
Best regards,
David
Hello David,
I was looking for this topic as I was having I think the same issue as @MHoblitz. I wish to export everything at once from BEM simulation, like one array with columns like WindSpeed, RotorCt, RotorCp, Power, Thrust, Torque etc…
I also noticed that there is no “BEM” menu as they are for the other module (like for example when I am in the “Blade design” module, there is a “Blade design” menu in the top ribbon), and this is where I was looking for the “Export data” option. I actually spent some time looking for it, I even checked an other version of QBlade to see if this was a bug of 2.0.8.
Anyway, I think it would be a very useful feature, and I think many people want to use QBlade to retrieve this Cp,Ct,Cq curves, as it is by far the most straightforward and user friendly.
Best regards,
Maximilien
Hi Maximilien,
you can export steady BEM performance tables in the “Multi BEM” module.
This allows you to not only vary rpm and windspeed, but also the pitch angle.
See the screenshot below.

hi!
when I exp0ort the data, the generated file is having all the data points in the same cell (I use excel for graphing the data). the other cells look like the have data in it, but are actually empty.
can I fix that somewhere?
thanks!

Hello Leon,
it looks like Excel isn’t recognizing the delimiter, which is why all your data appears in one cell. You can resolve this by using Excel’s “Text to Columns” feature or importing the file with the correct delimiter settings.
Please keep in mind that this forum is primarily focused on QBlade topics. Being a very general, Excel-related question, a quick web search would have likely provided you with a solution.

David
