Implementing theoretical materials analysis using computational science
In order to facilitate enhancing product performances and qualities and the efficiency of product design, it is necessary to elucidate and control physicochemical phenomena not only from a molecular and atomic level, but also at a micron level or less.
Computational science makes it possible to, for example, acquire mechanism and methods of enhancement by visualizing phenomena that are difficult to measure, such as atomic and molecular movement and changes in material structure. We utilize various computational software that correspond to diverse scales in our in-house product development.
