摘要：

A code that implements Einstein's equations in the characteristic formulation in 3D has been developed and thoroughly tested for the vacuum case. Here, we describe how to incorporate matter, in the form of a perfect fluid, into the code. The extended code has been written and validated in a number of cases where shocks do not form. It is stable and capable of contributing towards an understanding of a number of problems in black hole astrophysics. [S0556-2821(99)00614-1].
