Dear administrator(s), I have found a bug when trying to simulate a blade which consist in 2 cylindrical root stations (CD=1.2 for every Re) followed by 20 stations of S822 airfoil ( multi Re polars asigned). In the simulation, if Foil Interpolation option is selected, the program crashes and is closed abruptly (losing not saved data). If Foil interpolation is not selected, the programe runs normally. It seems that the program is not able to run when it comes, not only to interpolate within Re numbers,...

Dear, First of all, I would like to thank all the staff for such an user friendly and accurate software. I'm designing a VS-FP (passive stall regulated, 10 kW rated) for my Master Degree Final Project and after designing the blade on my own BEM code (Matlab) I have created the blade and performed the P-v and Cp-v characteristic curves in Q-Blade. The variable speed region is between U=2 m/s and U=6 m/s. I have done 2 simulations, one setting the Re number equal to 400000 for all the blade stations...
