We present a new implicit numerical discretization for the equations of radiation hydrodynamics (RHD) which is based on a more geometrical representation of a finite volume scheme suitable for spherical systems. In particular, the motion of the grid points is directly included by appropriate volume changes. Several examples illustrate the accuracy gained by this improved difference scheme.
