Title: Metamesh, Version 1.0

Abstract

Metamesh is a general-purpose C++ library for creating "mesh" data structures from smaller parts. That is, rather than providing a traditional "mesh format," as many libraries do, or a GUI for building meshes, Metamesh provides tools by which the mesh structures themselves can be built. Consider that a mesh in up to three dimensions can contain nodes (0d entities), edges (1d), faces (2d), and cells (3d). Edges are typically defined from two nodes. Faces can be defined from nodes or edges; and cells from nodes, edges, or faces. Someone might also wish to allow for general faces or cells, or for only a specific variant - say, triangular faces and tetrahedral cells. Moreover, a mesh can have the same or a lesser dimension than that of its enclosing space. In 3d, say, one could have a full 3d mesh, a 2d "sheet" mesh without cells, a 1d "string" mesh with neither faces nor cells, or even a 1d "point cloud." And, aside from the mesh structure itself, additional data might be wanted: velocities at nodes, say, or fluxes across faces, or an average density in each cell. Metamesh supports all of this, through C++ generics and template metaprogramming techniques. Usersmore » fit Metamesh constructs together to define a mesh layout, and Metamesh then automatically provides the newly constructed mesh with functionality. Metamesh also provides facilities for spinning, extruding, visualizing, and performing I/O of whatever meshes a user builds.« less
