Industrial concerns are very challenging for the computational materials science, and the challenge to such a realistic problem would expand applicability of first-principle electronic structure calculations. We have been collaborating with a couple of industrial companies to tackle a variety of realistic problems, and developing our software package, OpenMX, through experiences in such collaborations. As a result, OpenMX has been widely used for material researches in recent years. We will be able collaborate with researchers in company if both the sides can find mutual benefit for further development of materials science and technology and the software package, OpenMX. If you have any questions regarding the collaboration, please consult with us.
