Application of the data assimilation method incorporating conservation laws and constraints to the phase-field method

Year: 2019

Type: conference-paper

Abstract: Phase-field method has been used to simulate microstructural evolution in metal materials and is expected to help improving the efficiency of development and manufacturing process of materials. However, some of model parameters and materials values required in phase-field models are difficult to be identified. Recently, data assimilation methodologies based on Bayesian inference have been attracting attention for estimating such parameters and values by assimilating experimental data into phase-field simulations. In this study, we implement the data assimilation algorithm that can incorporate constrains such as the conservation law to the phase-field simulation and validate it by conducting numerical experiments.
