A particularly important area for such software infrastructure is mesh refinement5. This is essential to much current numerical-relativity research but is moderately difficult to implement even in only one spatial dimension, and much harder in multiple spatial dimensions. There are now a number of software libraries providing multi-dimensional mesh-refinement infrastructure (sometimes combined with parallelization), such as those listed in Table 1. The Cactus toolkit can be used in either unigrid or mesh-refinement modes, the latter using a “mesh-refinement driver” such as PAGH or Carpet [134, 131] (http://www.carpetcode.org).
In this review I point out event and apparent horizon finders which have been written in particular frameworks and comment on whether they work with mesh refinement.
