This thesis project in the field of numerical relativity aims to use compactification methods to tackle General Relativity on hyperboloidal slices, which allow the unambiguous evaluation of global spacetime properties at null infinity. The main objective is a free-evolution hyperboloidal axisymmetric implementation for a commonly used formulation of the Einstein equations. On the way towards the extraction of more accurate gravitational waveforms from the strong field regime, the code will be used to couple gravity to simple matter models, among them fundamental field candidates.
