The development in computers and the advance in general relativistic simulation techniques in the last years make it possible to perform precise computer experiments for systems of more than two bodies. Such systems exhibit a rich dynamics, but at the same time show a chaotic behaviour, i.e. the systems evolution is strongly dependent on the starting parameter of the configuration. For systems of multiple black holes, due to the strong gravitational radiation present in such systems, the accuracy of the initial data becomes of special importance.
Using the moving puncture approach systems of three black holes are simulated and the influence of accurate initial data is investigated with regard to the systems evolution and waveform.
