Outline of Final Research Achievements

I succeeded to introduce Einstein Toolkit, which is an open-use code of Einstein Equation Solver, although it does not solve the Einstein Equations so exactly. Independently, I developed another Einstein Equation Solver using "Puncture Method". I could develop the code successfully, and I could compare the quality of my code by solving same, simple test problems by my code and Einstein Toolkit.
