A new numerical code for the Bondi problem

doi: 10.6062/jcis.2009.01.02.002(Free PDF)


Henrique P. de Oliveira and E. L. Rodrigues


We present the first numerical code based on the Galerkin method to integrate the field equations of the Bondi problem. The Galerkin method is a spectral method whose main feature is to provide high accuracy with moderate computational effort. Several numerical tests were performed to verify the issues of convergence, stability and accuracy with promising results. This code opens up several possibilities of applications in more general scenarios for studying the evolution of spacetimes with gravitational waves.
