We will present a new version of our Force-Free Electrodynamics (FFE) numerical code in spherical coordinates that extrapolates the inner solar coronal magnetic field from a photospheric vector magnetogram. The code satisfies the photospheric boundary condition and the divergence-free condition to machine accuracy. Preliminary testing suggests that the performance of our method is comparable or better to that of other non-linear force-free extrapolations.
