Abstract
Volume meshes are generated through three-dimensional triangulation and
interior point creation based on the surface meshes. To deal with non-
convex geometries, boundarv surface conformity is gained via edge
swapping, boundarv edge and surface recovery, and the robustness of the
algorithm has been discussed in terms of the accuracy of geometric
judgments. The performance of the mesh generator has been investigated
by means of numerical experiments. and examples have been tested to
validate the mesh generator. The possibility of extension of this mesh
generator to incorporate with analysis programs, in terms of adaptive
analysis. has been explored. This paper is also designed to briefly
address mesh quality measures, qualitv statistics and mesh smoothing
techniques. Using mesh quality metrics, visual quality assessment has
been discussed. Furthermore, several general wavs of visual
representation of volume meshes have been introduced.
