We present a simple domain decomposition code based on theGalerkin-Collocation method to integrate the field equations of the Bondiproblem. The algorithm is stable, exhibits exponential convergence whenconsidering the Bondi formula as an error measure, and is computationallyeconomical. We have incorporated features of both Galerkin and Collocationmethods along with the establishment of two non-overlapping subdomains. We havefurther applied the code to show the decay of the Bondi mass in the nonlinearregime and its power-law late time decay. Another application is thedetermination of the wave-forms at the future null infinity connected withdistinct initial data.
