Foils in flow5

[@Triple_J.1]

techwinder, I believe the General Licence for xfoil allows for the sale of "wrapper" programs that build off of xfoil as in that agreement it is acknowledged that creators may still be compensated for their own contributions. If not, is there any way to work around the licensing by simply allowing a "drag and drop" folder where xfoil may be downloaded externally by the end user and combined to provide that functionality? I suppose its not so big of a problem to run xflr5 and flow5 separately and transfer data. I'm a longtime user of xflr, about to give Flow5 a try once I have a new aero project in mind.

You may be right but then I am not a lawyer and these are difficult matters for the layman. Besides expereience shows that having the foils analyzed in xflr5 and the results imported into flow5 is not much of a bother. Also I have too much respect for M. Drela and H. Youngren's work to go for a work-around. Lastly when flow5 is made opensource at some point in the future it will include XFoil as an integral module.

Hello, great work with flow5! Is there a way to read xfoil polars? Since Xflr5 is not scriptable, I was thinking about running a 2D analysis on xfoil and using those polars to run the scripted 3D analysis on flow5, is that a possible option? Xfoil exports polars in txt files, how can I load those in Flow5? Thank you for the help.

xflr5 is scriptable for foil analyses.

Flow5 v7.15, When I try to export to XFLR5 v6.48, it gives me an error "Could not open the file..." When I open it manually in XFLR5 and then run the analysis, and then manually try to import it back into Flow5, it gives me an error "Error reading line 3: Unrecognized Mach and Reynolds type. The polar(s) will not be stored."
