  The evolution of the stellar debris after tidal disruption due to the super
massive black hole's tidal force is difficult to solve numerically because of
the large dynamical range of the problem. We developed an SPH (Smoothed
Particle Hydrodynamics) - TVD (Total Variation Diminishing) hybrid code in
which the SPH is used to cover a widely spread debris and the TVD is used to
compute the stream collision more accurately. While the code in the present
form is not sufficient to obtain desired resoultion, it could provide a useful
tool in studying the aftermath of the stellar disruption by a massive black
hole.
