In this section we discuss some of the issues which have to be
confronted in a numerical implementation of the Einstein
equations and, in particular, of the conformal field equations to
solve the hyperboloidal initial value problem. The material
presented in this section is based to a large extent on work by
Hübner [76,
77,
78,
79,
81,
82] and Frauendiener [39,
38,
40,
41,
42]. These are also the references which should be consulted for a
more detailed discussion of the various numerical schemes. The
presentation here will be rather cursory in order to keep it
reasonably short.
