Abstract Scope |
Time-resolved X-ray computed tomography (4D-CT) is a powerful tool for observing three-dimensional dendrite growth during alloy solidification. However, reconstruction becomes difficult when the growth rate is high. In this study, we investigate the possibility of 3D reconstruction using phase-field simulation. Here, we use data assimilation to introduce the X-ray transmission images into the phase-field simulation. As the simulations in data assimilation becomes large-scale, we performed parallel computation using multiple GPUs on a GPU supercomputer. |
