The phase-field (PF) model has been used for simulating microstructure evolutions in various materials. However, likewise other simulation methods, since the PF model needs immeasurable parameters and unknown simulation conditions, the data assimilation (DA) attracts attention for reproducing realistic microstructure evolution by integrating experimental data to the PF simulation. In this study, we implement the ensemble Kalman filter to two-dimensional PF simulation of dendrite growth in Al-Cu alloy and estimate the strength of interfacial anisotropy which characterizes the morphology of dendrite. Our DA methodology is validated by conducting twin experiments and the true value of the interfacial anisotropy is successfully estimated.
