Visualization of 2-D and 3-D fields from its value in a finite number of points
Description
This work describes a method for the visualization of two- and three-dimensional fields, given its value in a finite number of points. These data can be originated in experimental measurements, numerical results, or any other source. For the field interpolation, the space is divided into simplices (triangles or tetrahedrons), using the Watson algorithm to obtain the Delaunay triangulation. Inside each simplex, linear interpolation is assumed. The visualization is accomplished by means of Finite Elements post-processors, capable of handling unstructured meshes, which were also developed by the authors. (Author)

En este trabajo se describe una metodologia para la visualizacion de campos bi- o tri-dimensionales, a partir de su valor en un numero determinado de puntos. Los mismos pueden provenir de mediciones experimentales, calculo numerico u otro origen. Para la interpolacion de la funcion se divide el recinto en simplices (triangulos o tetraedros) utilizando el algoritmo de Watson para obtener triangulaciones Delaunay; dentro de cada simplice se interpola linealmente. Para la etapa de visualizacion se utilizaron post-procesadores para elementos finitos ya existentes, capaces de trabajar con mallas no estructuradas. (Autor)Files
