报告摘要：Gravitational wave is among the most important theoretical predictions of general relativity. It has been directly detected very recently by LIGO successfully. Besides the advanced techniques involved in the experiment instruments, the theoretical model also played an important role in such a success. General speaking, a good model may increase the detection ability more than 100 times for a given hardware. In order to treat the real objects in the universe which does not admit any symmetry and includes many complex physics, numerical method is the only practical method currently. For Einstein equation, even the numerical method is highly non-trival. A bundle of tricks are needed to model the gravitational wave sources. Besides the tricks, a huge computer software is needed to treat the massive computational cost problem. Besides general relativity, almost all existing gravity theories predict the existence of gravitational wave. In the near future, it is possible to use gravitational wave detection to test different gravitational theories if proper model is available. This talk will discuss these related problems in general.
