Abstract:
This paper presents an algorithm for the fully automatic mesh generation for the finite element analysis of ships and offshore structures. The quality requirements on the mesh generator are imposed by the acceptance criteria of the classification societies as well as the need to avoid shear locking when using low degree shell elements. The meshing algorithm will be generating quadrilateral dominated meshes (consisting of quads and triangles) and the mesh quality requirements mandate that quadrilaterals with internal angles close to 90° are to be preferred. The geometry is described by a dictionary containing points, rods, surfaces, and openings. The first part of the proposed method consists of an algorithm to automatically clean the geometry. The corrected geometry is then meshed by the frontal Delaunay mesh generator as implemented in the gmsh package. We present a heuristic method to precondition the cross field of the fronatal quadrilateral mesher. In addition, the influence of the order in which the plates are meshed will be explored as a preconditioning step.

Abstract:
Konuya Ermeni hadiselerini araştıranların pek fazla dikkat etmedikleri bir hususu açıklamakla başlamak istiyoruz. XIX. yüzyılın son çeyreğinde Osmanlı İmparatorluğu'nda ortaya çıkan veya çıkarılan Ermeni hadisesi nedir ve bundan ne anlamak gerekir? Kanaatimize göre bu sorunun cevabı çok önem arzetmektedir. Zira, bu soruya verilecek cevaba göre Ermeni hadisesi incelenip, yorumlanabilir. O halde, her şeyden evvel Ermeni hadisesinin ne olduğu ve kime göre neyi ifade ettiği muhakkak açıklığa kavuşturulmalıdır. Evvela, Ermeni hadisesi nedir? derken arkasından üç soru daha akla gelmektedir. Şöyle ki, Ermeni hadisesi "siyasî bir mesele midir"? "siyasî bir macera mıdır"? "siyasî bir isyan mıdır"? Ayrıca, kimin için "mesele", kimin için "macera" ve nihayet kimin için "isyan" olduğu hususu da önem kazanmaktadır. Çünkü, taraflara göre konunun mahiyeti değişir. Şimdi bu hususlar üzerinde biraz durmayı faydalı görüyoruz.

Abstract:
The study proposes a fast flexible direct power flow solution for radial distribution systems and a fast flexible direct weakly meshed power flow solution for weakly meshed distribution systems. The algorithm is based on the direct forward sweep power flow solution, which is an updated version of the backward/forward sweep solution. The fast flexible direct power flow uses a unique conversion matrix (CM) to rapidly determine the power flow solution. The inverted conversion matrix and its slide-modified matrix are used to solve the power flow problem in a single forward sweep step, which is a novel feature of this work. To ensure the invertibility of the conversion matrix, it is constructed to have a small condition number and a determinant of minus one, and all of its eigenvalues must be equal to that of minus one. Additionally, by modifying the conversion matrix to accommodate the loop branch using the break-point idea, a new weakly meshed conversion matrix (WMCM) is generated with the same following modification as for the radial network and employed in the fast flexible direct weakly meshed power flow (FFDWMPF) solution for the weakly meshed distribution network. The usage of a single matrix in the power flow solution and advanced direct techniques decreases the number of iterations and CPU execution time when MATLAB programming is executed. Furthermore, the proposed method is flexible enough to incorporate any changes in the radial or weakly meshed distribution system just by incorporating the changes in the CM and WMCM for any radial or weakly meshed system. Moreover, the robustness of FFDPF and FFDWMPF is evaluated under various loading scenarios on balanced radial and weakly meshed distribution networks. Finally, to validate the proposed algorithm, the proposed strategy is applied to numerous balanced and unbalanced distribution systems.

Abstract:
An adaptive method for producing anisotropic quasi-structured meshes is presented in this thesis. Current anisotropic adaptation schemes produce meshes without any regular structure which can hurt accuracy and efficiency of the solution. By modifying the anisotropic adaptation schemes, producing aligned, quasi-structured meshes is possible which means that the accuracy and efficiency of the flow solution are improved. By using quasi-structured meshes, we can get the advantages of flexibility of unstructured meshes for complex geometries and accuracy of the high directional qualities of the structured meshes at the same time. The construction of the quasi-structured meshes from initial isotropic unstructured meshes is accomplished by assigning metrics to vertices based on the error estimation methods. The metrics are used to communicate the desired anisotropy to the meshing program. After assigning a metric to each vertex, the mesh is refined anisotropically using four mesh quality improvements operations to produce high quality anisotropic quasi-structured meshes: swapping to choose the diagonal of the quadrilateral formed by two neighboring triangles which results the maximum quality, inserting vertices for large triangles, vertex removal to eliminate small edges and vertex movements to optimize the location of the vertices so that quasi-structured meshes are created. The idea in the optimization process is to smooth a vertex location by seeking so that the final mesh contains target elements dictated by the metrics assigned in the three vertices of that triangle. The final, high quality mesh is produced by using these operations iteratively based on the metrics assigned to each vertex in an adaptive, solution-based process.

Abstract:
L’objectif principal de cette thèse est de concevoir une méthode d’optimisation de structures qui jouitd’une description exacte (i. E. Au moyen d’un maillage) de la forme à chaque itération du processus, touten bénéficiant des avantages de la méthode des lignes de niveaux lorsqu’il s’agit de suivre leur évolution. Indépendamment, on étudie également deux problèmes de modélisation en optimisation structurale. Dans une première partie bibliographique, on présente quelques notions classiques, ainsi qu’un état del’art sommaire autour des trois thématiques principales de la thèse - méthode des lignes de niveaux (Chapitre1), optimisation de formes (Chapitre 2) et maillage (Chapitre 3). La seconde partie de ce manuscrit traite de deux questions en optimisation de formes, celle de la répartitionoptimale de plusieurs matériaux au sein d’une structure donnée (Chapitre 4), et celle de l’optimisation robustede fonctions dépendant du domaine lorsque des perturbations s’exercent sur le modèle (Chapitre 5). Dans une troisième partie, on étudie laconception de schémas numériques en lien avec la méthode deslignes de niveaux lorsque le maillage de calcul est simplicial (et potentiellement adapté). Le calcul de ladistance signée à un domaine est étudié dans le chapitre 6, et la résolution de l’équation de transport d’unefonction ‘level set’ est détaillée dans le chapitre 7. La quatrième partie (Chapitre 8) traite des aspects de la thèse liés à la modification locale de maillagessurfaciques et volumiques. Enfin, la dernière partie (Chapitre 9) détaille la stratégie conçue pour l’évolution de maillage en optimisation de formes, à partir des ingrédients des chapitres 6, 7 et 8
The main purpose of this thesis is to propose a method for structural optimization which combines theaccuracy of featuring an exact description of shapes (i. E. With a mesh) at each iteration of the process withthe versatility of the level set method for tracking their evolution. Independently, we also study two problemsrelated to modeling in structural optimization. In the first, bibliographical part, we present several classical notions, together with some recent developmentsabout the three main issues of this thesis - namely level set methods (Chapter 1), shape optimization(Chapter 2), and meshing (Chapter 3). The second part of this manuscript deals with two issues in shape optimization, that of the optimalrepartition of several materials within a fixed structure (Chapter 4), and that of the robust optimization offunctions depending on the domain when perturbations are expected over the considered mechanical model. In the third part, we study the design of numerical schemes for performing the level set method onsimplicial (and possibly adapted) computational meshes. The computation of the signed distance functionto a domain is investigated in Chapter 6, and the resolution of the level set advection equation is presentedin Chapter 7. The fourth part (Chapter 8) is devoted to the meshing techniques introduced in this thesis. Eventually, the last part (Chapter 9) describes the proposed strategy for mesh evolution in the contextof shape optimization, relying on the numerical ingredients introduced in Chapters 7, 8, 9

Abstract:
This thesis deals with digital watermarking methods for copyright protection of 3-D surface meshes and mesh sequences. The proposed methods are based on wavelet analysis of the geometry of the surface meshes, or on wavelet analysis of the vertex coordinate signals along the time axis. Static meshes. The first proposal embeds the watermark into the L2 norm of the geometric wavelet coefficients. The Cartesian coordinates should be converted into the spherical coordinates. For the invariance of the wavelet coefficients after inverse wavelet transform, it is necessary to synchronize the connectivity by re-ordering the vertex indexes from a reference vertex. This approach ensures the blind detection which does not require the original meshes during watermark extraction procedures. The second proposal is based on a statistical approach. The histogram of the L2 norm of scale coefficients was divided into regular bins. The mean or the variance of each bin is modified according to the watermark by a non-linear exponential transformation. The watermark can be extracted from the distribution of the scale coefficients after wavelet analysis, as well as from the distribution of vertex norms of the watermarked meshes without using the wavelet analysis. Mesh sequence with fixed connectivity. Our proposals are based on the vertex coordinate signals along the time axis. The watermark is incorporated into the wavelets coefficients of each coordinates or into the vertex norm signal wavelet coefficients or scales coefficients
Cette thèse propose des méthodes de protection des droits d’auteur, par tatouage numérique, d'objets en trois dimensions représentés par leur maillage triangulaire surfacique. Les approches proposées utilisent la décomposition en ondelettes du maillage ou des signaux associés à l’évolution des coordonnées des sommets de ce maillage au cours du temps. Maillages statiques. Une première proposition, incorpore le tatouage dans le module des coefficients d’ondelettes. Elle nécessite la transformation des coordonnées cartésiennes des sommets en coordonnées sphériques. Après la transformée en ondelettes inverse, les index des sommets sont réordonnés, afin d’assurer une invariance des coefficients d’ondelettes. Cette approche garantit l’extraction du tatouage sans le maillage original. Une deuxième proposition utilise une approche statistique. Elle incorpore le tatouage dans le module des coefficients d’échelles, par intervalles de leur histogramme. La moyenne ou la variance de chaque intervalle est modifiée par le tatouage à l’aide d’une transformation non linéaire exponentielle. Le tatouage peut être extrait, sans le maillage original, à partir de la distribution des coefficients d’échelle ou directement sur le maillage en pleine résolution. Séquences de maillages à connectivité constante. L'évolution temporelle des coordonnées des sommets est assimilée à trois signaux indépendants et le tatouage est incorporé dans les coefficients d’ondelettes de chacune des coordonnées, dans ceux du module de chaque sommet ou d'échelle de ce dernier signal

Full text
Abstract:
On examine ici deux concepts fondamentaux touchant la genèse et la structure du système platonicien, en proposant de les rapporter à deux modèles empruntés à la mathématique ancienne. Le premier est un postulat, usuellement désigné sous le nom d’axiome d’Eudoxe – Archimède, le second un algorithme de calcul : l’anthyphérèse. Tous deux ressortissent à la théorie mathématique développée par Théétète à la suite des travaux logistiques de Théodore ; il a semblé que leur articulation constituait le socle théorique de la réponse platonicienne à la thèse protagoréenne de l’homo mensura. On a suggéré de replacer cette dernière dans le cadre d’une polémique ancienne regardant la consistance du concept mathématique de mesure, dont la notion naïve fut remise en cause par la découverte successive des rapports incommensurables puis d’ensembles non–archimédiens : les angles mixtilignes. Cela impliquait de réexaminer les rapports possibles entre mathématiques et sophistique : on a choisi à cet effet l’exemple de la quadratrice d’Hippias d’Élis. Il convenait aussi d’envisager la liaison étroite qu’entretiennent la dialectique platonicienne et cette science métrétique rénovée que Platon nomme «juste mesure». On a tenté de montrer comment celle-ci pouvait informer certains procédés de celle-là, à partir de l’étude de quelques passages des dialogues qui jalonnent la dernière période de Platon. La théorie de la division appliquée aux Idées, comme l’analyse et la constitution des mixtes cosmologique, politique et individuel ont ainsi paru pouvoir être examinées dans le cadre de cette hypothèse
Two mathematical notions seem to structure Plato’s theory of measure. The first one is a postulate, usually known as the “Eudoxus axiom”, the other an algorithm called “anthuphairesis”. Both of them belonged to the mathematical theory developed by Theaetetus expanding Theodorus’ logistics. The main hypothesis of this work is that they constitute the core of Plato’s response against the Homo mensura thesis elaborated by Protagoras. We have thus proposed to replace Protagoras’ theory in the enlarged context of a serious crisis affecting the logical consistency of the mathematical notion of measure, provoked by the discovery of incommensurable magnitudes as well as non–Archimedean sets, exemplified by mixtilinear angles. This implied to examine anew the links between ancient sophistic and mathematics, and particularly Plato’s critics against Hippias’ quadratrix. It was also required to study the close relation between platonic dialectic and the new art of measurement exposed by Plato in the Statesman. Thus, by studying some passages mainly taken from Plato’s last dialogues, an attempt has been made to show how the higher art of measurement could inform dialectics. Plato’s theory of division, as well as the analysis and the generation of the mixed structures which constitute the universe, the city and the individual man have thus been tentatively reduced to this model

Abstract:
Automated tetrahedral meshing from manifold tessellated optical scan data is investigated to determine its viability as an approach for finite element analysis. This approach avoids the costs of constructing a volumetric representation of the scan data that can be meshed with conventional grid generation approaches. This paper demonstrates an auto-meshing algorithm for inserted airfoil and integrally bladed rotor hardware. These automatically generated models are compared to experimentally obtained frequencies and mode shapes for validation. In an effort to compare the fidelity as well as the effect of mesh density on analytical convergence rate, manually generated all-hexahedral models are compared against the auto-meshed tetrahedral finite element models. CPU time, solution accuracy, and mesh convergence are evaluated to determine the viability of automatically generated tetrahedral meshes versus the standard approach of manually generating hex-dominant meshes. This paper demonstrates that given the power of modern CPUs, automatically generated all-tetrahedral meshes can serve as a viable alternative to manually generated hex-dominant finite element models, especially when these meshes can be refined for solution convergence within the auto-mesher. This new approach effectively solves both the mesh convergence problem while demonstrating that models based on as-measured geometry can be rapidly built with virtually no human interaction.

Abstract:
Abstract Many existing computer-aided design systems for MEMS require the generation of a three-dimensional mesh for computational analysis of the microdevice. Mesh generation requirements for microdevices are very complicated because of the presence of mixed-energy domains and the different numerical techniques implemented for each energy domain. For example, volume meshes are employed for finite-element analysis of structural deformation and surface meshes are employed for boundary-element analysis of electrostatic forces on the structure. This paper describes a meshless technique, using which the analysis of a complicated microdevice can be performed by sprinkling points instead of generating a mesh.

Full text
Abstract:
Abstract A fully-automatic free-form mesh generation method is described in this paper. The related mesh generator is capable of meshing planar regions. In addition to being fully-automatic, the method produces quadrilateral or triangular elements with aspect ratios near one. The input to the method includes the region’s boundary curves, the element size, and the mesh grading information. The method begins by decomposing the planar region to be meshed into convex subregions. Each subregion is meshed by first generating nodes on its boundaries using the input element size. The boundary nodes are then offset to mesh the subregion. The resulting meshes are merged together to form the final mesh. The free-form mesh generator and its related method has been tested and applied to a wide number of regions. Sample examples are presented.

Abstract:
Abstract This paper reports on a project in which automatic mesh generation is divided into two phases. In the first phase feature recognition and shape grammar techniques, based on the medial axis of a 2D region, are employed to decompose a complex component into a number of simple subregions. In the second phase the subregions are meshed to a controlled density using conventional mapped mesh methods. The advantage of this approach is that good quality meshes of quadrilateral elements can be generated in 2D and, potentially, meshes of hexahedral elements in 3D. A parallel program of work has concentrated on the analysis of errors: different methods for error estimation and for providing transitions in mesh density have been compared.

Abstract:
Abstract This report presents a new finite element meshing approach, put forth by Q-Mesh, to producing 3-D mesh models for solid objects whose geometries can be captured with an industrial computed tomography (CT) scanner. The Q-Mesh system utilizes a series of deformable grid templates and component solid regions to create a 3-D global mesh that can be divided into subregions of connected meshes located within the component solids. It provides an interactive graphics interface through which the user can design and visualize 3-D, multiregion meshes consisting of well-formed wedge and hexahedron elements. The unique solid-modeling algorithm implemented in Q-Mesh allows the system to generate, automatically, matching finite element meshes across any number of solid regions. This unique feature makes Q-Mesh an ideal mesh generator for finite element solvers geared to the simulation of general multiregion problems. Furthermore, the use of a multiregion mesh model as the source for analysis models representing variations of a single-region mesh, as unions of selected subregions, has proven more time efficient and cost effective than the single-region alternative where each variational model has to be regenerated from scratch. This report focuses on the utility of a CT scanner as a geometry input processor to Q-Mesh. The generation of finite element models for a solid object represented in the form of sliced CT scan data involves two phases: (1) converting the sliced CT scan data into a series of stacked solids; and (2) utilizing Q-Mesh’s interactive design tools to build mesh models based on the reconstructed solids. A number of examples are given to demonstrate the general procedure and unique capabilities of the new meshing approach.

"An Exploration of Accuracy and Convergence of the Degenerate Uniform Strain Hexahedral Element: A Solution to the Unmeshed Void in an All-Hexahedral Mesh."

Full text
Abstract:
The uniform strain hexahedral element mesh has long been a work horse for getting accurate and convergent answers in high deformation solid mechanics analyses. Obtaining an all-hexahedral mesh can be a difficult and time consuming process thus limiting the element’s use in design phase computations. Unconstrained paving and plastering offers a technique to get an all-hexahedral mesh automatically but still can leave un-meshable voids [1]. While degenerated forms of the uniform strain hexahedral element such as the wedge have been used sparingly, they have garnered limited general acceptance. We present a more exhaustive numerical exploration of the degenerated hexes with the hope of encouraging their use to resolve the un-meshable voids. The results of patch tests are used to numerically demonstrate linear completeness of the degenerate elements. A manufactured solution analysis is then used to show optimal convergence rates for meshes containing degenerate elements. Additionally, applications to a torsion rod and high velocity impact are used to highlight the accuracy and applicability of degenerates for solving more complex problems.

Full text
Abstract:
Uncertainty in loading has been treated by probabilistic methods and by fuzzy set methods. Fuzzy finite element method (FFEM) that calculates, given possible bounds of the applied loads, sharp bounds on displacements and stresses are available in the literature. However, FFEM requires a structured mesh to perform the underlying finite element analysis. It is generally recognized that the creation of workable meshes for complex geometric configurations can be difficult, time consuming, and expensive. This discrepancy is further exacerbated when solving solid mechanics problems characterized by a continuous change in the geometry of the domain under analysis. The underlying structures of these methods, which rely on a mesh, are cumbersome in treating moving cracks or mesh distortion. Consequently, the only viable option when applying FEM is to remesh during each discrete step of the model’s evolution. This creates numerical difficulties, even for deterministic analysis, and often leads to degradation in solution accuracy, complexity in computer programming, and a computationally intensive environment. Consequently, there is considerable interest in eliminating or greatly simplifying the meshing task. In recent years, a class of Galerkin-based meshfree or meshless methods have been developed that do not require a structured mesh to discretize the problem, such as the element-free Galerkin method, and the reproducing kernel particle method. These methods employ a moving least-squares approximation method that allows resultant shape functions to be constructed entirely in terms of arbitrarily placed nodes. Meshless discretization presents significant advantages for modeling fracture propagation. By sidestepping remeshing requirements, crack-propagation analysis can be dramatically simplified. Since mesh generation of complex structures can be far more time-consuming and costly than the solution of a discrete set of linear equations, the meshless method provides an attractive alternative to FEM. However, most of the development in meshless methods to date has focused on deterministic problems. Research into fuzzy meshless analysis has not been widespread and is only now gaining attention. Due to inherent uncertainties in loads, material properties and geometry, a fuzzy meshless model is ultimately necessary. Hence, there is considerable interest in developing fuzzy meshless methods capable of addressing uncertainties in loads, material properties and geometry, and of predicting the probabilistic response. This paper presents a new fuzzy meshless method for interval of the fracture parameters due to variability in the mechanical and load properties using fuzzy set approach.

Abstract:
In the stochastic mechanics community, the need to account for uncertainty has long been recognized as key to achieving the reliable design of structural and mechanical systems. It is generally agreed that advanced computational tools must be employed to provide the necessary computational framework for describing structural response. A currently popular method is the stochastic finite element method (SFEM), which integrates probability theory with the standard finite element method (FEM). However, SFEM requires a structured mesh to perform the underlying finite element analysis. It is generally recognized that the creation of workable meshes for complex geometric configurations can be difficult, time consuming, and expensive. This discrepancy is further exacerbated when solving solid mechanics problems characterized by a continuous change in the geometry of the domain under analysis. The underlying structures of these methods, which rely on a mesh, are cumbersome in treating moving cracks or mesh distortion. Consequently, the only viable option when applying FEM is to remesh during each discrete step of the model’s evolution.

Abstract:
This documents describes several studies undertaken to assess the applicability of MultiLevel Monte Carlo (MLMC) methods to problems of interest; namely in turbulent fluid flow over civil engineering structures. Several numerical experiments are presented wherein the convergence of quantities of interest with mesh parameters are studied at different Reynolds’ numbers and geometries. It was found that MLMC methods could be used successfully for low Reynolds’ number flows when combined with appropriate Adaptive Mesh Refinement (AMR) strategies. However, the hypotheses for optimal MLMC performance were found to not be satisfied at higher turbulent Reynolds’ numbers despite the use of AMR strategies. Recommendations are made for future research directions based on these studies. A tentative outline for an MLMC algorithm with adapted meshes is made, as well as recommendations for alternatives to MLMC methods for cases where the underlying assumptions for optimal MLMC performance are not satisfied.

Full text
Abstract:
Unconstrained magnetotelluric inversion commonly produces insufficient inherent resolution to image ore-system fluid pathways that were structurally thinned during post-emplacement tectonic activity. To improve the resolution in these complex environments, we synthesized the 3-D magnetotelluric (MT) response for geologically realistic models using a finite-element-based forward-modelling tool with unstructured meshes and applied it to the Lalor volcanogenic massive-sulfide deposit in the Snow Lake mining camp, Manitoba. This new tool is based on mapping interpolated or simulated resistivity values from wireline logs onto unstructured tetrahedral meshes to reflect, with the help of 3-D models obtained from lithostratigraphic and lithofacies drillhole logs, the complexity of the host-rock geological structure. The resulting stochastic model provides a more realistic representation of the heterogeneous spatial distribution of the electric resistivity values around the massive, stringer, and disseminated sulfide ore zones. Both models were combined into one seamless tetrahedral mesh of the resistivity field. To capture the complex resistivity distribution in the geophysical forward model, a finite-element code was developed. Comparative analyses of the forward models with MT data acquired at the Earth's surface show a reasonable agreement that explains the regional variations associated with the host rock geological structure and detects the local anomalies associated with the MT response of the ore zones.
