Abstract
JAXA and Kyoto University are researching with quality engineering tools (JIANT) and wallstat, a seismic simulator for wooden buildings.
Our theme is research on the combination of testing and simulation (data assimilation).This study is a joint research of JAXA-Kyoto University-Osaka Institute of Techinology.

Reasons and benefits of using JAXA Supercomputer System
The purpose of using a supercomputer is to speed up calculations.
The calculation of wallstat takes 40 minutes per case on a general PC.
That means that if we perform 6000 calculations in one case study, it takes a total of 160 days, but if we use JSS3, we can complete them in a few hours.
Achievements of the Year
As a research with Kyoto University Research Institute for Humanosphere, we studied data assimilation under multiple design targets/environmental conditions this year (Fig1). This time, we focused on a three-story building and adjusted it for two buildings and two seismic waves. Since good results were obtained, we made a presentation at the 27th Annual Meeting of the Society for Computational Engineering and Science (June 2022). At the conference, we won the 2022 Technology Award.
