Outline of Final Research Achievements

In FY2016, I surveyed papers or books as "inspection of the mathematical characteristic of the shape function satisfying delta function property" and "investigation of present application of the meshless method".
In FY2017, I applied a shape function satisfying delta function property to Finite-Difference Time-Domain Method. As a result, computational accuracy and stability improved, but a computational increased.
I resigned from RIKEN Advanced Institute for Computational Science before the end during a period, and broke off a study.
