Notes:
The kinetics and topology of ideal grain growth were simulated using the phase-fieldmodel. Large scale phase-field simulations were carried out where ten thousands grains evolved intoa few hundreds without allowing coalescence of grains. The implementation was first validated intwo-dimensions by checking the conformance with square-root evolution of the average grain sizeand the von Neumann-Mullins law. Afterwards three-dimensional simulations were performedwhich also showed fair agreement with the law describing the evolution of the mean grain sizeagainst time and with the results of S. Hilgenfeld et al. in 'An Accurate von Neumann's Law forThree-Dimensional Foams', Phys. Rev. Letters, 86(12)/2685, March 2001. Finally the steady stategrain size distribution was investigated and compared to the Hillert theory
