Abstract Scope |
This study proposes a new Bayesian data assimilation (DA) method using the variational autoencoder (VAE) for a phase-field modeling. The proposed DA enables us to integrate the microstructure features extracted from the microstructure images using the VAE into the phase-field simulation in the latent space. In this paper, we investigate the performance of DA method by conducting numerical experiments where parameters included in the phase-field model of spinodal decomposition in a binary system and the multi-phase-field model for grain growth are estimated from the microstructure feature. The results of numerical experiments reveal that the parameters can be accurately estimated using a few latent variables that capture the noticeable microstructural change. |
