But my graphs for wing are not being generated, I wanna make an airfoil which i have to test in a wind tunnel at about 18 m/s or near by. I decrease both the cord length and span with Reynold number ranging from 1e^+5 to 1e^+10, and i take angle in range of -15 to 20. It shows an error of unconverged and sometime, when i vary data ,it gives "some points are outside the flight envelope". Can you please tell me what should it do.
Did you try going to the graphs tab at the top and editing that (I used 4 graphs). Right clicking over the graphs and changing the settings may also help.
