High Quality Bi-Linear Transfinite Meshing with Interior Point Constraints
نویسنده
چکیده
For a variety of structural finite element analyses on automotive body panels, aerospace wings and space satellite panels, highquality, structured quadrilateral meshing is imperative. Transfinite meshing, the technique to produce such meshes is severely infringed by the presence of surface-interior point constraints. The present paper attempts to solve the inverse problem of transfinite meshing with interior point cointraints. A modified Newton Raphson based solution is proposed to inverse solve Coons bi-linear blending equation. The Coons parametric coordinates are thus determined for a set of face-interior points from their global coordinates. The boundary of the surface is next seeded with "soft-points" at reflected locations and smart-discretized to result in high fidelity, high-quality transfinite meshes.

CSALF-Q: A Bricolage Algorithm for Anisotropic Quad Mesh Generation
“Bricolage”, a multidisciplinary term used extensively in visual arts, anthropology and cultural studies, refers to a creation that borrows elements from a diverse range of existing designs. The term is applied here to describe CSALF-Q, a new automatic 2D quad meshing algorithm that combines the strengths of recursive subdivision, loop-paving and transfinite interpolation to generate surface me...
متن کاملFlattening 3D Triangulations for Quality Surface Mesh Generation
A method of flattening 3D triangulations for use in surface meshing is presented. The flattening method supports multiple boundary loops and directly produces planar locations for the vertices of the triangulation. The general nonlinear least-square fit condition for the triangle vertices includes conformal (angle preserving) and authalic (area preserving) conditions as special cases. The metho...
متن کاملA Transfinite Meshing Approach for Body-In-White Analyses
A very wide range of finite element analyses required to design carbodies calls for quadrilateral meshes with austere quality needs. Quadrilaterals being varying strain and non-planar, element quality, in body-in-white analyses, is virtually impossible to measure with a single parameter. Auto-designers mostly prefer heuristic element quality metrices that catapult the need for predominantly ort...
متن کاملInnnite Dimensional Quadratic Optimization: Interior-point Methods and Control Applications
An innnite-dimensional convex optimization problem with the linear-quadratic cost function and linear-quadratic constraints is considered. We generalize the interior-point techniques of Nesterov-Nemirovsky to this innnite-dimensional situation. The obtained complexity estimates are similar to nite-dimensional ones. We apply our results to the linear-quadratic control problem with quadratic cons...
متن کاملMulti-sided Surfaces with Fullness Control
Multi-sided surfaces are important in several areas of Computer-Aided Geometric Design, including curve network based design, approximation of triangular meshes, hole filling, and so on. In the majority of surface representations, the boundary constraints entirely determine the interior of these patches, however, frequently there is a need to have additional design freedom for shaping the surfa...
