Quite interesting research work, thanks Eytan Adler! Wanted to let you guys know that your efforts to present your work on a public forum are helping undergrad students, like me from India, to appreciate what we are learning in the classroom.

Really nice studies and impressive slides!

yep the problem with XFOIL, there is no subroutine implemented to stop if the local Machnumber exceed 1, or if the local pressure coefficient is lower than the critical pressure coefficient.
