　　摘要：

　　Detecting gravitational wave directly is hard. Partly, this is because constructing

　　the theoretical model for gravitational wave sources is hard. A good gravitational wave model

　　can not only improve the detection sensitivity of a given instrument but also provide

　　basis for source parameter extraction from gravitational wave detection. Such modeling

　　is hard because solving Einstein's equations is hard with respect to realistic celestial

　　objects. Analytical method is impossible to treat this problem currently.

　　Even using numerical method to treat this problem is highly non-trivial. How to convert

　　Einstein's equations to an numerically solvable problem? How to make the numerically

　　solving process stable? How to numerically solve the problem quickly and accurately enough?

　　I will touch these issues in this talk. In addition, I will introduce the AMSS-NCKU numerical

　　relativity code which is developed by our group. Some related applications of AMSS-NCKU

　　code will be discussed.
