Non-Simplicial Delaunay Meshing via Approximation by Radical Partitions

چکیده

We consider the construction of a polyhedral Delaunay partition as limit sequence power diagrams (radical partitions). The dual Voronoi diagram is obtained weighted partitions. problem reduced to two convex polyhedra, inscribed and superscribed around circular paraboloid, pairs general polyhedra. primal polyhedra should converge polyhedron converges polyhedron. are interested in case when vertices can move or merge together, i.e., no new faces allowed for These rules define transformation set initial spheres into using radius variation sphere movement elimination. Existence theorems still unavailable but we suggest functional measuring deviation from one paraboloid. It discrete Dirichlet function which linear interpolant vertical distance functional's absolute minimizer attained on constant field, meaning that be by simple translation. This formulation surface not quadratic since unknowns polyhedron, hence, unique. concentrate experimental confirmation approach viability put aside mesh quality problems. zero value gradient proposed defines manifold describing evolution spheres. Hence, Delaunay-Voronoi meshes optimized constraint.

Hierarchical Delaunay Triangulation for Meshing

This paper discusses an elliptical pad structure and its polygonal approximation. The elliptical pad is a part of via model structures, which are important and critical components on today’s multilayered Printed Circuit Board (PCB) and electrical packaging. To explore meshing characterization of the elliptical pad helps mesh generation over 3D structures for electromagnetic modeling (EM) and si...

Lattices on simplicial partitions

In this paper, (d + 1)-pencil lattices on simplicial partitions in Rd are studied. The barycentric approach naturally extends the lattice from a simplex to a simplicial partition, providing a continuous piecewise polynomial interpolant over the extended lattice. The number of degrees of freedom is equal to the number of vertices of the simplicial partition. The constructive proof of this fact l...

On Nonobtuse Simplicial Partitions

This paper surveys some results on acute and nonobtuse simplices and associated spatial partitions. These partitions are relevant in numerical mathematics, including piecewise polynomial approximation theory and the finite element method. Special attention is paid to a basic type of nonobtuse simplices called path-simplices, the generalization of right triangles to higher dimensions. In additio...

Meshing Piecewise Linear Complexes by Constrained Delaunay Tetrahedralizations

We present a method to decompose an arbitrary 3D piecewise linear complex (PLC) into a constrained Delaunay tetrahedralization (CDT). It successfully resolves the problem of non-existence of a CDT by updating the input PLC into another PLC which is topologically and geometrically equivalent to the original one and does have a CDT. Based on a strong CDT existence condition, the redefinition is d...

Localized Delaunay Refinement for Sampling and Meshing

The technique of Delaunay refinement has been recognized as a versatile tool to generate Delaunay meshes of a variety of geometries. Despite its usefulness, it suffers from one lacuna that limits its application. It does not scale well with the mesh size. As the sample point set grows, the Delaunay triangulation starts stressing the available memory space which ultimately stalls any effective p...
