A Guaranteed Quality Boundary Graded Triangular Meshing Algorithm Backed by a Computer-Assisted Proof
نویسندگان
چکیده
The quality of mesh elements including shape and size influences the performance of finite elements analysis, interpolation, and contouring. The existence of small angles is especially critical for conditioning of the stiffness matrix in finite elements methods. In this paper we present a boundary graded triangular mesh generation algorithm that allows for guaranteed bounds on angles. Our proof program shows that our algorithm bounds the minimum angle above 5.65◦.

Quality Meshing of 2D Images with Guarantees Derived by a Computer-Assisted Proof
This paper describes an algorithm for generating unstructured triangular meshes from a continuous two-dimensional object represented by an image. The algorithm uses squares as a background grid from which to build the quadrilateral elements that conform to the input contours. Then the triangulation is obtained by automatically choosing the diagonals that optimize the angles of the triangles. Th...
متن کاملGuaranteed-quality triangular mesh generation for domains with curved boundaries
Guaranteed-quality unstructured meshing algorithms facilitate the development of automatic meshing tools. However, these algorithms require domains discretized using a set of linear segments, leading to numerical errors in domains with curved boundaries. We introduce an extension of Ruppert’s Delaunay refinement algorithm to domains with curved boundaries and prove that the same quality bounds ...
متن کاملQuality guaranteed all-hex mesh generation by a constrained volume iterative fitting algorithm
The hexahedral mesh (hex mesh) is usually preferred to the tetrahedral mesh (tet mesh) in finite element methods for numerical simulation. In finite element analysis, a valid hex mesh requires that the scaled Jacobian value at each mesh vertex is larger than 0. However, the hex mesh produced by lots of prevailing hex mesh generation methods cannot be guaranteed to be a valid hex mesh. In this p...
متن کاملParallel 2D Graded Guaranteed Quality Delaunay Mesh Refinement
We develop a theoretical framework for constructing guaranteed quality Delaunay meshes in parallel for general two-dimensional geometries. This paper presents a new approach for constructing graded meshes, i.e., meshes with element size controlled by a user-defined criterion. The sequential Delaunay refinement algorithms are based on inserting points at the circumcenters of triangles of poor qu...
متن کاملDevelopment of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
