Integrated Simulation System for Soft Materials
J-OCTA is an integrated simulation system for materials research and development
J-OCTA is the software that supports understanding of mechanisms and estimation of material properties from the atomic scale to the micrometer scale in the development of a wide variety of materials, such as rubbers, plastics, thin films, coatings, and electrolytes.
It can be used as a knowledge discovery tool to understand complicated properties and phenomena that could not be fully grasped through experimental results alone.
This product uses OCTA
, which was developed through industry-university cooperative project.
