Hi all,

I have 6 camber profiles for geona with Camber/Chord as 30,26,23,20,16, and 13 respectively. I am trying to find out coefficients of lift for different geona's profile with same Mainsail profile interaction. I also changed the grid to fine, coarse and Medium ( medium being the grid with scale factor 1). So total number of meshes I have become 6*3 = 18.

Now for every mesh, I get approx same values for coefficients of lift for same cambers, but values differs for different cambers( which is expected). I have to analyse why the values of different grids give different values for same camber, as values are approximately same but not same.

Can someone guide me some research papers to refer to for the same? Also any comments and guidelines will be beneficial to me.
