Quadtree and Octree Grid Generation
Engineering analysis often involves the accurate numerical solution of boundary value problems in discrete form. Hierarchical quadtree (or octree) grid generation offers an efficient method for the spatial discretisation of arbitrary-shaped two- (or three-) dimensional domains. It consists of recursive algebraic splitting of sub-domains into quadrants (or cubes), leading to an ordered hierarchi...
متن کاملParametrization-Independent Elliptic Surface Grid Generation
The generation of computational grids on surfaces of three-dimensional configurations is an important component of many areas of computational research, both as a boundary grid for volume grid generation or to perform computations on the surface. For reasons of computational efficiency, structured grids remain widely used in areas such as the computation of aerodynamic flows. Elliptic grid gene...
متن کاملElliptic Grid Generation with B-Spline Collocation
We revisit the lassi al te hnique of ellipti grid generation with harmoni mappings. For the determination of the ontrol fun tions we use the framework developed by Spekreijse [1℄. However, instead with nite di eren es we dis retize the underlying partial di erential equation with a B-spline ollo ation method in order to work dire tly with the native data representations of our CAGD system. This...
متن کاملElliptic Grid Control on a Discrete Level
Considering a grid cell with a single central point the solution of the discretized Laplace equation may be conceived as a weighted average of points on the cell boundary. Our grid control method is based on a local perturbation of the numerical solution to the Laplace equation by specifying line-wise central target points relative to the orientation of and the distance from the cell’s bounding...
متن کاملMultilevel First-Order System Least Squares for Elliptic Grid Generation
A new fully-variational approach is studied for elliptic grid generation (EGG). It is based on a general algorithm developed in a companion paper [10] that involves using Newton’s method to linearize an appropriate equivalent first-order system, first-order system least squares (FOSLS) to formulate and discretize the Newton step, and algebraic multigrid (AMG) to solve the resulting matrix equat...
