    En aquesta tesis es presenta un nou marc per validar i generar malles corbes d¿alt ordre per models geomètrics complexos. La aplicació principal dels mètodes proposats és la generació de malles aptes per a realitzar anàlisis amb elements finits mitjançant mètodes d¿alt ordre no-estructurats. És important recalcar que la manca d¿un mallador robust i automàtic per malles corbes és un dels problemes principals que ha obstaculitzat la introducció dels mètodes d¿alt ordre a la indústria. Concretament, sense malles corbes d¿alt ordre composades per elements vàlids i tal que encaixi amb el contorn del domini, les taxes de convergència dels mètodes d¿alt ordre no es poden assolir. La motivació principal d¿aquest treball és, per tant, proporcionar un nou marc que corregeixi aquestes mancances.En primer lloc, proposem una nova mesura de distorsió (qualitat) per malles corbes de qualsevol grau polinòmic. Les mesures presentades permeten validar si una malla d¿alt ordre és apta per a l¿anàlisi d¿elements finits amb mètodes d¿alt ordre no-estructurats. En particular, donat un element d¿alt ordre, la mesura de qualitat assigna valor zero si l¿element és invàlid, i valor u si l¿element es correspon amb la configuració ideal triada (mida i distribució nodal desitjades). A més a més, demostrem que si la qualitat d¿un element és major que zero, la regió en la que el determinant de la Jacobiana de l¿element és no-positiva té mesura zero. Presentem diversos exemples per il¿lustrat que les mesures proposades poden ser usades per validar malles d¿alt ordre isotròpiques i de capa límit.En segon lloc, desenvolupem un mètode per suavitzar i desenredar malles d¿alt ordre. Específicament, proposem una minimització no-lineal global de la mesura de distorsió. La distorsió és regularitzada per tal de permetre desenredar malles que continguin elements invàlids. D¿altra banda, el procés d¿optimització preserva, quan és possible, diverses característiques geomètriques de la malla lineal (forma dels elements, costats rectes, i mida). Per mitjà de diversos exemples mostrem que la implementació del procés d¿optimització és robusta i capaç de lidiar amb configuracions en les que la malla inicial conté un gran nombre d¿elements invàlids. Considerem casos amb malles de fins a grau polinòmic deu, grans deformacions dels contorns corbs, contorns còncaus, i malles de capa límit amb un grans compressions.En tercer lloc, estenem la definició de mesura de distorsió i qualitat a malles corbes d¿alt ordre amb els nodes en superfícies parametritzades. Usant aquesta definició, proposem també un procediment de suavitat i desenredat per malles en superfícies CAD. Aquest procediment està expressat en termes de les coordenades paramètriques dels nodes de la malla per imposar que els nodes estiguin sempre sobre la geometria CAD. A la vegada, demostrem que el procediment és independent de la parametrització de la superfície. Per tant, el mètode pot optimitzar malles a superfícies CAD que estiguin definides per parametritzacions de baixa qualitat. Finalment, proposem un nou mètode per generar malles corbes d¿alt ordre, mitjançant un procediment a posteriori. El procediment consisteix en modificar una malla linear introduint primer nodes d¿alt ordre. En segon lloc, es desplacen els nodes de contorn per assegurar que estan exactament sobre la superfície CAD. I en tercer lloc, es suavitza i desenreda la malla per tal d¿obtenir una malla final d¿alt ordre corba que sigui vàlida. Finalment, incloem diversos exemples on mostrem que les malles generades són aptes per a realitzar anàlisis amb elements finits mitjançant mètodes no-estructurats d¿alt ordre.

    This thesis is divided into three separate volumes, which are consistent with the indifferent order in which they could be read. Two of them are dedicated to two masters of modern architecture, Mies and Utzon, who respectively personify two major architectural currents which share with unequal intensity the first half of the twentieth century: rationalism and realism or organic architecture. The third volume presents some important platforms of the architecture of Mesopotamia, Egypt and Greece, that shortlist of three architectural cultures which, according to Giedion, embodied the first spatial conception of architecture. This volume is presented here as an annex, as this thesis mainly analyzes various notions of platforms built during the twentieth century. But it was precisely from the reinterpretation of the platform, classical in essence, that those magnificent massive platforms of the antiquity rightly claimed their modern relevance. Both Mies and Utzon not only delimited their respective projects between two substantially horizontal layers, that of the ground and that of the roof, but also the formal characteristics of each of these episodes defined the key attributes and interests of their architecture. In both cases, however, it has been the plane of the roof which has raised more analysis and recognition: - In the case of Mies, his roofs, straight and flat without exception, have been the result of the evolution of certain structural typologies, in concrete and later on in steel, which also fulfilled a conception of programme that prioritized flexibility ahead of functionality . - In the case of Utzon, his deliberately wavy roofs, invariably of concrete, have been the most distinctive figurative feature of all his architecture, eclipsed under the impact of his most celebrated work, the Sydney Opera House. However, for the understanding of the architecture, of both Mies and Utzon, it would be erroneous not to put the episodes of their respective roofs in relation to their ground planes, mostly understood as platforms. It is necessary to believe therefore that the numerous essays that have focused on the top plane, that of the roof as the preferred objective of analysis or even as the only one, of their respective works, have done so knowing this dual relationship, assuming this reductionism as a strategy for a greater analytical depth. This work poses a similar license, focused in this case, however, on the other horizontal plane, the one underneath, the ground level, significantly less explored and, in the opinion of the author, equally relevant. From this reduction of the focal field, where the platform becomes the epicentre of the projects of both architects, this thesis has been carried out to state that: -Both in the case of Mies and in the one of Utzon, the use of the platform, far from being an isolated fact, became a constant in each of their respective careers. - Except for a few exceptions, determined by singular requirements of the environment or the programme, all of their respective platforms are massive, far from the light horizontal planes with which modern architecture was built. - Both in one case as in the other, the platform is systematically used as a mediation space, to interact with the environment and determine the limits of the project and as transition space (where one passes), to build the visual approach system of the compound. -Starting from a certain moment, corresponding to the mature stage of both architects, Platform and Access united an inseparable binomial, prevalent in the construction of ground floors of their respective architectures, which gave place to an episode, that of the elevated access, which characterized all of their work. The platform became the threshold of their architectures.

    We present a technique to extend Jacobian-based distortion (quality) measures for planar triangles to high-order isoparametric elements of any interpolation degree on CAD parameterized surfaces. The resulting distortion (quality) measures are expressed in terms of the parametric coordinates of the nodes. These extended distortion (quality) measures can be used to check the quality and validity of a high-order surface mesh. We also apply them to simultaneously smooth and untangle high-order surface meshes by minimizing the extended distortion measure. The minimization is performed in terms of the parametric coordinates of the nodes. Thus, the nodes always lie on the surface. Finally, we include several examples to illustrate the application of the proposed technique.

    We present a technique to extend any distortion (quality) measure for planar meshes to meshes on parameterized surfaces. The resulting distortion (quality) measure is expressed in terms of the parametric coordinates of the nodes. This extended distortion (quality) measure can be used to check the quality and validity of both triangle and quadrilateral surface meshes. We also apply it to simultaneously smooth and untangle surface meshes by minimizing the extended distortion measure. The minimization is performed in terms of the parametric coordinates of the nodes and therefore, the nodes always lie on the surface. Finally, we include several examples to illustrate the applicability of the proposed technique. Specifically, we extend several Jacobian-based measures, and we us them to smooth and untangle triangle and quadrilateral meshes on CAD surfaces.

    Two of the most successful methods to generate unstructured hexahedral meshes are the grid-based methods and the advancing front methods. On the one hand, the grid-based methods generate high quality elements in the inner part of the domain using an inside-outside approach. On the other hand, advancing front methods generate high quality hexahedra near the boundary using an outside-inside approach. In this paper we propose the receding front method, an original approach that combines the advantages of both methodologies: we use an inside-outside mesh generation approach by means of a reversed front advance. We apply this approach to mesh outer domains. To reproduce the shape of the boundaries, we first precompute the mesh fronts by combining two solutions of the Eikonal equation on a tetrahedral reference mesh. Then, to generate high quality elements, we expand the quadrilateral surface mesh of the inner body towards the unmeshed external boundary using the pre-computed fronts as a guide. Further research is under way in order to apply the proposed method to more complicated geometries.

    One of the most used algorithms to generate hexahedral meshes for extrusion volumes is the multi-sweeping method. The algorithm decomposes the geometry into many-to-one sub-volumes and then meshes each sub-volume separately. However, the quality of the final mesh depends on the decomposition process. First, the location of inner nodes created during the decomposition process may induce bad quality elements. To avoid this drawback, we propose a three-stage decomposition process to locate those nodes. Second, the imprinting process is not robust when dealing with non-planar surfaces. For this reason, we introduce the new concept of the computational domain. The computational domain is a planar representation of the levels of the geometry. In this way, we improve the operations needed to perform imprints.

    One of the most widely used algorithms to generate hexahedral meshes in extrusion volumes with several source and target surfaces is the multi-sweeping method. However, the multi-sweeping method is highly dependent on the final location of the nodes created during the decomposition process. Moreover, inaccurate location of inner nodes may generate erroneous imprints of the geometry surfaces such that a final mesh could not be generated. In this work, we present a new procedure to decompose the geometry in many-to-one sweepable volumes. The decomposition is based on a least-squares approximation of affine mappings defined between the loops of nodes that bound the sweep levels. In addition, we introduce the concept of computational domain, in which every sweep level is planar. We use this planar representation for two purposes. On the one hand, we use it to perform all the imprints between surfaces. Since the computational domain is planar, the robustness of the imprinting process is increased. On the other hand, the computational domain is also used to compute the projection onto source surfaces. Finally, the location of the inner nodes created during the decomposition process is computed by averaging the locations computed projecting from target and source surfaces.

    Esta tesis versa sobre el desarrollo de las tecnologías para la generación de mallas de hexaedros. El proceso de generar una malla de hexaedros no es automático y su generación requiere varias horas te trabajo de un ingeniero especializado. Por lo tanto, es importante desarrollar herramientas que faciliten dicho proceso de generación. Con este fin, se presenta y desarrolla un método de proyección de mallas, una técnica de sweeping o barrido, un algoritmo para la obtención de mallas por bloques, y un entorno de generación de mallas. Las implementaciones más competitivas del método de sweeping utilizan técnicas de proyección de mallas basadas en métodos afines. Los métodos afines más habituales presentan varios problemas relacionados con la obtención de sistemas de ecuaciones normales de rango deficiente. Para solucionar dichos problemas se presenta y analiza un nuevo método afín que depende de dos parámetros vectoriales. Además, se detalla un procedimiento automático para la selección de dichos vectores. El método de proyección resultante preserva la forma de las mallas proyectadas. Esta proyección es incorporada también en una nueva herramienta de sweeping. Dicha herramienta genera capas de nodos internos que respetan la curvatura de las superficies inicial y final. La herramienta de sweeping es capaz de mallar geometrías de extrusión definidas por trayectorias curvas, secciones no constantes a lo largo del eje de sweeping, y superficies inicial y final con diferente forma y curvatura.En las últimas décadas se han propuesto varios ataques para la generación automática de mallas de hexahedros. Sin embargo, todavía no existe un algoritmo rápido y robusto que genere automáticamente mallas de hexaedros de alta calidad. Se propone un nuevo ataque para la generación de mallas por bloques mediante la representación de la geometría y la topología del dual de una malla de hexaedros. En dicho ataque, primero se genera una malla grosera de tetraedros. Después, varió polígonos planos se añaden al interior de los elementos de la malla grosera inicial. Dichos polígonos se denotan como contribuciones duales locales y representan una versión discreta del dual de una malla de hexaedros. En el último paso, la malla por bloques se obtiene como el dual de la representación del dual generada. El algoritmo de generación de mallas por bloques es aplicado a geometrías que presentan diferentes características geométricas como son superficies planas, superficies curvas, configuraciones delgadas, agujeros, y vértices con valencia mayor que tres.Las mallas se generan habitualmente con la ayuda de entornos interactivos que integran una interfaz CAD y varios algoritmos de generación de mallas. Se presenta un nuevo entorno de generación de mallas especializado en la generación de cuadriláteros y hexaedros. Este entorno proporciona la tecnología necesaria para implementar les técnicas de generación de mallas de hexaedros presentadas en esta tesis.

    This thesis deals with the development of hexahedral mesh generation technology. The process of generating hexahedral meshes is not fully automatic and it is a time consuming task. Therefore, it is important to develop tools that facilitate the generation of hexahedral meshes. To this end, a mesh projection method, a sweeping technique, a block-meshing algorithm, and an interactive mesh generation environment are presented and developed. Competitive implementations of the sweeping method use mesh projection techniques based on affine methods. Standard affine methods have several drawbacks related to the statement of rank deficient sets of normal equations. To overcome these drawbacks a new affine method that depends on two vector parameters is presented and analyzed. Moreover, an automatic procedure that selects these two vector parameters is detailed. The resulting projection procedure preserves the shape of projected meshes. Then, this procedure is incorporated in a new sweeping tool. This tool generates inner layers of nodes that preserve the curvature of the cap surfaces. The sweeping tool is able to mesh extrusion geometries defined by non-linear sweeping trajectories, non-constant cross sections along the sweep axis, non-parallel cap surfaces, and cap surfaces with different shape and curvature. In the last decades, several general-purpose approaches to generate automatically hexahedral meshes have been proposed. However, a fast and robust algorithm that automatically generates high-quality hexahedral meshes is not available. A novel approach for block meshing by representing the geometry and the topology of a hexahedral mesh is presented. The block-meshing algorithm first generates an initial coarse mesh of tetrahedral elements. Second, several planar polygons are added inside the elements of the initial coarse mesh. These polygons are referred as local dual contributions and represent a discrete version of the dual of a hexahedral mesh. Finally, the dual representation is dualized to obtain the final block mesh. The block-meshing algorithm is applied to mesh geometries that present different geometrical characteristics such as planar surfaces, curved surfaces, thin configurations, holes, and vertices with valence greater than three.Meshes are usually generated with the help of interactive environments that integrate a CAD interface and several meshing algorithms. An overview of a new mesh generation environment focused in quadrilateral and hexahedral mesh generation is presented. This environment provides the technology required to implement the hexahedral meshing techniques presented in this thesis.
