  We present a new code designed to solve the equations of classical ideal
magneto-hydrodynamics (MHD) in three dimensions, submitted to a constant
gravitational field. The purpose of the code centers on the analysis of solar
phenomena within the photosphere-corona region. We present 1D and 2D standard
tests to demonstrate the quality of the numerical results obtained with our
code. As solar tests we present the transverse oscillations of Alfvenic pulses
in coronal loops using a 2.5D model, and as 3D tests we present the propagation
of impulsively generated MHD-gravity waves and vortices in the solar
atmosphere. The code is based on high-resolution shock-capturing methods, uses
the HLLE flux formula combined with Minmod, MC and WENO5 reconstructors. The
divergence free magnetic field constraint is controlled using the Flux
Constrained Transport method.
