| Mesh Description | Continuous phase-field grid; spatial scale calibrated to match experimentally observed grain morphology (~10–50 μm grain sizes) |
| Software / Package | Custom Allen-Cahn phase-field model (NOT classical FEM); implemented based on thermodynamic grain selection theory |
| Physics / Study Type | Allen-Cahn equation (eq 14): ∂φq/∂t = −Lq(T) δF/δφq; free energy functional F includes: local free energy density (Landau expressions) + grain boundary energy (gradient term κq); competition between surface energy (ΔΓsurface) and strain energy (ΔFstrain) governs grain selection |
| Solver / Study Settings | Explicit time integration (Allen-Cahn); t=0 to t=400 time steps shown; phase variables φq evolve to minimize total free energy F |
| Geometry / Model Dimension | 2D domain; electroplated film deposited layer-by-layer on substrate; scale bar 50 μm (Figures 2, S3, S5, S6) |
| Boundary / Initial Conditions | 75 grains nucleated randomly at t=0 on substrate (bottom of domain); solid case: nucleation at contact points (imperfect solid-solid contact); grains randomly assigned to (001), (101), or (111) orientation |
