  We develop a 3 dimensional computer code to study a coalescing neutron star
binary. The code can currently follow the evolution up to two stars begin to
merge from two spherical stars of mass 1 solar mass and radius 8.9km with
separation 35.4km. As for coordinate conditions, we use conformal slicing and
pseudo-minimal distortion conditions. The evolution equations for the metric is
integrated using the CIP method while the van Leer's scheme is used to
integrate the equations for the matter. We present a few results of our
simulations including gravitational radiation.
