A Level-Set Method for the Evolution of Faceted Crystals
نویسندگان
چکیده
A level-set formulation for the motion of faceted interfaces is presented. The evolving surface of a crystal is represented as the zero-level of a phase function. The crystal is identified by its orientation and facet speeds. Accuracy is tested on a single crystal by comparison with the exact evolution. The method is extended to study the evolution of a polycrystal. Numerical examples in two and three dimensions are presented.

Simulation of faceted film growth in three dimensions: microstructure, morphology and texture
We present the results of a series of simulations of the growth of polycrystalline, faceted films in three spatial dimensions. The simulations are based upon the assumptions of the well known van der Drift model in which the growth rate of each surface is fixed only by its crystallographic orientation. The simulation method is based upon the level-set formalism and the only input are the relati...
متن کاملTOPOLOGY OPTIMIZATION OF PLANE STRUCTURES USING BINARY LEVEL SET METHOD AND ISOGEOMETRIC ANALYSIS
This paper presents the topology optimization of plane structures using a binary level set (BLS) approach and isogeometric analysis (IGA). In the standard level set method, the domain boundary is descripted as an isocountour of a scalar function of a higher dimensionality. The evolution of this boundary is governed by Hamilton–Jacobi equation. In the BLS method, the interfaces of subdomai...

متن کاملPhysically Derived Rules for Simulating Faceted Crystal Growth using Cellular Automata
We derive a set of algorithms for simulating the diffusion-limited growth of faceted crystals using local cellular automata. This technique has been shown to work well in reproducing realistic crystal morphologies, and the present work provides a more rigorous physical foundation that connects the numerical code to the physics of attachment kinetics and diffusion dynamics. We then apply these a...
