Abstract Scope |
Recent work has demonstrated a new mode filter grain growth model based on the same underlying theory as the Monte Carlo Potts model but can leverage GPU-compatible Python libraries with a relatively simple algorithm to provide computationally fast isotropic and anisotropic grain growth simulations. This study follows up on this work, exploring the interpretability of the mode filter and the ability to learn mode filter kernels, which are used to fundamentally control grain growth behavior. We show that the kernel can be used to learn inclination-dependent grain growth governed by variations in energy and mobility. We then demonstrate that this learned kernel input into the mode filter to simulated sequences of grain growth that mimics the original growth behavior. We show results from a variety of example microstructures (e.g., circle grains, hexagonal grains, polycrystals) and anisotropic scenarios (e.g., elongation from anisotropic energies and mobilities). |
