The polar for cl vs alpha is smooth. So is cl vs cd and cl/cd vs alpha.
Why is it then, that the cm vs alpha polar is all jaggedy? (At least when using XFLR5.). What is there about an airfoil-shaped that makes cm different?
It can't be a jagged airfoil-shaped because I always refine it to 120 points.
