DESCRIPTION:ABSTRACT: In recent years there has been an increased interest
  in modelling the nonlinear dynamics in theories beyond general relativity
 . Recent work by different groups has provided a new pathways towards perf
 orming numerical relativity simulations in such theories. In this talk\, I
  summarize subset of these ideas and will illustrate them in the context o
 f k-essence\, a subset of Horndeski theory. In particular\, I will present
  and example where different extensions (or UV completions) of the theory 
 allow for continuing the evolution past the Cauchy breakdown of the origin
 al theory.
