LaGriT (Los Alamos Grid Toolbox)

Abstract

LaGriT is a library of user callable tools that provide mesh generation, mesh optimization and dynamic mesh maintenance in three dimensions for a variety of applications. Geometric regions within arbitrarily complicated geometries are defined as combinations of bounding surfaces, where the surfaces are described analytically or as collections of points in space. A variety of techniques for distributing points within these geometric regions are provided. Mesh generation uses a Delaunay tetrahedralization algorithm that respects material interfaces and assures that there are no internal negative coupling coefficients. The data structures created to implement this algorithm are compact and powerful and expandable to include hybrid meshes as well as tetrahedral meshes.
