There are few packages to convert 2D airfoil data to 3D wing data. One option is to use a computational fluid dynamics (CFD) software package, such as ANSYS Fluent or OpenFOAM, to perform the 3D analysis. CFD software can simulate the flow around a 3D wing and calculate the lift and drag coefficients, including the effects of tip vertices and induced drag.
There are other tools like XFOIL/XFLR5 also. XFOIL has the capability to calculate the 2D lift and drag coefficients of an airfoil as a function of angle of attack (alpha), and it can also calculate the 3D lift and drag coefficients of a wing using the lifting-line theory.
For post-stall analysis, you may need to use a more advanced method, such as a vortex lattice method or a panel method, to account for the complex flow behavior that occurs at high angles of attack. These methods are available in some CFD software packages.
