Hi,

Anybody having 2D field panel method source code. Any pointer to available source code will also be helpfull.

Thanks

Hi,
I'm working on a 2D unsteady panel method for harmonic oscillations of a NACA 0012 airfoil. I've been trying to debug the code for ages. I'm getting a nice sinosoidal variation for the lift force but the value of amplitudes are not satisfactory. Does anyone have any source to verify the values I'm getting. Also, while implementing the kutta condition(Basu and Hancock), I'm getting a quadratic equation. So, to choose the correct root, the one closest to the last time step values is chosen. But at even slightly higher frequencies, the two roots are very close and the code doesn't converge anymore. So, I want to know whether there is a better way to choose the correct root so that I can reach higher frequencies.

Thank You.
