Abstract
In numerical relativity there would seem to be considerable advantages in combining Cauchy and characteristic methods in different regions o f spacetime. Numerical experiments demonstrate, for the model problem of the scalar wave equation in flat space using general null coordinat es, that there are no unforseen problems with the interface between th e two regions
