QualMesh software can produce a quality volume or a surface mesh for a polyhedral domain (has to be a manifold). The mesh is a Delaunay mesh. It is designed on the principle of Delaunay refinement but can take inputs with small angles. Standard Delaunay refinement cannot handle inputs with angles less than nienty degrees. The software is based on recent results described in the paper given below. The algorithm guarantees that almost all triangles and tetrahedra have bounded radius-edge ratio except few ones(skinny) in the vicinity of small input angles.
We have Qualmesh-surface for meshing polyhedral surfaces and Qualmesh-volume
for meshing the volume bounded by such a surface. The volume meshing is slow is currently getting improved...we will put an improved version soon.
