Along with the development of computer environment and computational technique, large-scale physics-based simulations have been realized. In addition, accumulation of “big data” has raised expectations for BDEC (big data & extreme-scale computing). In digital twin concept, an example of BDEC, simulation has to be performed repeatedly and thus, stability of the simulation is important. In this study, we realized stabilized soil liquefaction analysis with a high-resolution large-scale soil-structure model.
