 * **MagIC** uses either Chebyshev polynomials or finite differences in the radial direction and spherical harmonic decomposition in the azimuthal and latitudinal directions.  MagIC supports several Implicit-Explicit time schemes where the nonlinear terms and the Coriolis force are treated explicitly, while the remaining linear terms are treated implicitly.
