MODELING Unlike other models that have been used to simulate the solidification of a macroscopic part, our model incorporates three distinct length scales to simulate the microstructure: a coarse grid for the heat diffusion, a fine grid for tracking the solid fraction evolution and an unstructured grid for tracking the shape of individual spherulites and the lamellae within them.
