Computational Methods for Microstructure Covolume Techniques of Discretization
Abstract
This work covers one of the basic computational issues in materials science, which is that of devising algorithms for computing microstructure. Finite element discretizations are used to approximate a standard energy density functional. Grid effects are found to affect the solutions in some cases and suitable remedies are investigated. Covolume methods are a second topic of research. Three dimensional error estimates are obtained. A new and optimal Voronoi-Delaunay mesh generator is given. Microstructure computations, covolume methods, Voronoi-Delaunay meshes.
