| Outline of Final Research Achievements |
We successfully develop a new neutrino radiation hydrodynamic code for core-collapse supernovae using M1-Closure scheme. The features of the code and the obtained results are described in Kuroda et al. 2016. The matrix inversion scheme used in the code is well-tuned and we got a few times of speed up from the original one.
Another achievement in this study is the code comparison between the other groups. That was urgent issue for the community of supernova models since the results obtained in one group is different from other groups. After the careful check, we found the difference originate from the input physics they employed not the numerical schemes.
