  We have performed a first fully 3-D GRMHD simulation with Schwarzschild black
hole with a free falling corona. The initial simulation results show that a jet
is created as in the previous simulations using the axisymmetric geometry with
the mirror symmetry at the equator. However, the time to generate the jet is
longer than in the 2-D axisymmetric simulations. We expect that due to the
additional freedom in the azimuthal dimension without axisymmetry with respect
to the z axis and reflection symmetry with respect to the equatorial plane, the
dynamics of jet formation can be modified. Further simulations are required for
the study of instabilities along the azimuthal direction such as
accretion-eject instability
