Glass molding is a key technology of manufacturing for optical devices, but trial-and-error for finding a best molding condition is a problem.
We aim to solve it by simulation.
Based on an elastic-plastic structural analysis solver developed in RIKEN, we will develop a simulation code analyzing physical phenomena specific to glasses, as viscoelasticity or structural relaxation, measure physical properties of various optical glasses, cooperate with ray-tracing simulation, and realize a glass molding and optics simulation software for optics manufacturing.
