Automatic Curvilinear Quality Mesh Generation Driven by Smooth Boundary and Guaranteed Fidelity
Jing Xu, Andrey N. Chernikov · Procedia Engineering · 2014
The development of robust high-order finite element methods requires the construction of valid high-order meshes for complex geometries without user intervention. This paper presents a novel approach for automatically generating a high-order mesh with two main features: first, the boundary of the mesh is globally smooth; second, the mesh boundary satisfies a required fidelity tolerance. Invalid elements are eliminated. Example meshes demonstrate the features of the algorithm.
