We present a new adaptive-harmonic structured grid generation method. It is based on a functional that shares a common set of minimizers with Ivanenko’s harmonic functional [9]. An unconstrained optimization process related to a continuation parameter is used to guarantee the convexity of the grid cells. Several numerical examples of grids generated on(More)
The present work shows two approaches to the generation of orthogonal or quasi-orthogonal grids applying similar techniques to those implemented by Barrera-Sánchez and Tinoco-Ruiz [Ph.D. Thesis, CIMAT, 1997] on the construction of smooth and convex grids, considering linear combinations of functionals defined over the grid as little perturbations to(More)
Abstract. In this paper, we address the problem of generating good quality grids on very irregular regions, and propose a measure for both the quality of the generated grids and the difficulty of the problem, as well as an efficient algorithm based on the minimization of area functionals to solve it. Using the proposed measure, a preliminary classification(More)
