4 Numerical Issues

In this section we discuss some of the issues that 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 [89Jump To The Next Citation Point90Jump To The Next Citation Point91Jump To The Next Citation Point92Jump To The Next Citation Point94Jump To The Next Citation Point95Jump To The Next Citation Point] and Frauendiener [45Jump To The Next Citation Point46Jump To The Next Citation Point47Jump To The Next Citation Point48Jump To The Next Citation Point49Jump To The Next Citation Point]. 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.
