Resumo:

The frame field distributed inside the model region characterizes the singular structure features inside the model. These singular structures can be used to decompose the model region into multiple quadrilateral structures, thereby generating a block-structured quadrilateral mesh. For the generation of block-structured quadrilateral mesh for two-dimensional geometric models, a convolutional neural network model is proposed to identify the singular structure inside the model contained in the frame field. By training the network model with a large number of model region decomposition data obtained in advance, the model can identify the vectors of the frame field in the region located in the segmentation field. Then, the segmentation streamline is constructed from the annotation. Based on this, the geometric region is decomposed into several small regions, regions which are then discretized with quadrilateral mesh elements. Finally, through two geometric models, it is verified that the convolutional neural network model proposed in this study can effectively identify the singular structure inside the model to realize the model region decomposition and block-structured mesh generation.

Abstract We report the development of a nested block-structured adaptive mesh framework to solve multidimensional, time-dependent hyperbolic equations encountered in astrophysics. An approach based on a tabular list is used to construct variants of Hilbert space-filling curves in an iterative fashion to maintain the connectivity of locally refined mesh configurations using a doubly linked list. Modifications are made to conventional boundaries of computational blocks to aid the adaptive mesh. We also describe a well-defined, computationally efficient data structure to hold self-similar mesh units for this purpose. The flexibility of this code is demonstrated by the performance of various Riemann solvers implemented in this computational framework.

AbstractAiming at a complex multi-block structured grid, an efficient dynamic mesh generation method is presented in this paper, which is based on radial basis functions (RBFs) and transfinite interpolation (TFI). When the object is moving, the multi-block structured grid would be changed. The fast mesh deformation is critical for numerical simulation. In this work, the dynamic mesh deformation is completed in two steps. At first, we select all block vertexes with known deformation as center points, and apply RBFs interpolation to get the grid deformation on block edges. Then, an arc-length-based TFI is employed to efficiently calculate the grid deformation on block faces and inside each block. The present approach can be well applied to both two-dimensional (2D) and three-dimensional (3D) problems. Numerical results show that the dynamic meshes for all test cases can be generated in an accurate and efficient manner.

AbstractIn this paper, a hybrid dynamic mesh generation method for multi-block structured grid is presented based on inverse distance weighting (IDW) interpolation and transfinite interpolation (TFI). The major advantage of the algorithm is that it maintains the effectiveness of TFI, while possessing the ability to deal with multi-block structured grid from the IDW method. In this approach, dynamic mesh generation is made in two steps. At first, all domain vertexes with known deformation are selected as sample points and IDW interpolation is applied to get the grid deformation on domain edges. Then, an arc-length-based TFI is employed to efficiently calculate the grid deformation on block faces and inside each block. The present approach can be well applied to both two-dimensional (2D) and three-dimensional (3D) problems. The proposed method has been well-validated by several test cases. Numerical results show that dynamic meshes with high quality can be generated in an accurate and efficient manner.

Esta dissertação é parte de um amplo projeto de pesquisa, que visa ao desenvolvimento de uma plataforma computacional de dinâmica dos fluidos (CFD) capaz de simular a física de escoamentos que envolvem mistura de várias espécies químicas, com reação e combustão, utilizando um método hibrido Simulação de Grandes Escalas (LES) / Função Densidade Filtrada (FDF) Lagrangiana em malha adaptativa, bloco-estruturada. Uma vez que escoamentos com mistura proporcionam fenômenos que podem ser correlacionados com a combustão em escoamentos turbulentos, uma visão global da fenomenologia de mistura foi apresentada e escoamentos fechados, laminar e turbulento, que envolvem mistura de duas espécies químicas inicialmente segregadas foram simulados utilizando o código de desenvolvimento interno AMR3D e o código recentemente desenvolvido FDF Lagrangiana de composição. A primeira etapa deste trabalho consistiu na criação de um modelo computacional de partículas estocásticas em ambiente de processamento distribuído. Isto foi alcançado com a construção de um mapa Lagrangiano paralelo, que pode gerenciar diferentes tipos de elementos lagrangianos, incluindo partículas estocásticas, particulados, sensores e nós computacionais intrínsecos dos métodos Fronteira Imersa e Acompanhamento de Interface. O mapa conecta informações Lagrangianas com a plataforma Euleriana do código AMR3D, no qual equações de trans- porte são resolvidas. O método FDF Lagrangiana de composição realiza cálculos algébricos sobre partículas estocásticas e provê campos de composição estatisticamente equivalentes aos obtidos quando se utiliza o método de Diferenças Finitas para solução de equações diferenciais parciais; a técnica de Monte Carlo foi utilizada para resolver um sistema derivado de equações diferenciais estocásticas (SDE). Os resultados concordaram com os benchmarks, que são simulações baseadas em plataforma de Diferenças Finitas para solução de uma equação de transporte de composição filtrada.
This master thesis is part of a wide research project, which aims at developing a com- putational fluid dynamics (CFD) framework able to simulate the physics of multiple-species mixing flows, with chemical reaction and combustion, using a hybrid Large Eddy Simulation (LES) / Lagrangian Filtered Density Function (FDF) method on adaptive, block-structured mesh. Since mixing flows provide phenomena that may be correlated with combustion in turbulent flows, we expose an overview of mixing phenomenology and simulated enclosed, ini- tially segregated two-species mixing flows, at laminar and turbulent states, using the in-house built AMR3D and the developed Lagrangian composition FDF codes. The first step towards this objective consisted of building a computational model of notional particles transport on distributed processing environment. We achieved it constructing a parallel Lagrangian map, which can hold different types of Lagrangian elements, including notional particles, particu- lates, sensors and computational nodes intrinsic to Immersed Boundary and Front Tracking methods. The map connects Lagrangian information with the Eulerian framework of the AMR3D code, in which transport equations are solved. The Lagrangian composition FDF method performs algebraic calculations over an ensemble of notional particles and provides composition fields statistically equivalent to those obtained by Finite Differences numerical solution of partially differential equations (PDE); we applied the Monte Carlo technique to solve a derived system of stochastic differential equations (SDE). The results agreed with the benchmarks, which are simulations based on Finite Differences framework to solve a filtered composition transport equation.

L'objectif de cette thèse est d'apporter de nouvelles solutions pour améliorer les performances lors de la résolution numérique d'équations aux dérivées partielles en étudiant une méthode de génération de maillages quadrilatéraux basée sur des champs de croix.Notre approche repose sur l'alignement d'un champ de croix donné par rapport au bord du domaine de calcul, suivi du partitionnement de ce dernier en régions à quatre côtés que l'on maillera ensuite en quadrilatères. Cela nous permet de générer un maillage structuré par bloc tout en préservant la position des singularités du champ de croix initial. Pour ce faire, nous mettons en place une étude théorique des champs de croix nous permettant d'identifier les conditions sous lesquelles un champ de croix donné permet effectivement de partitionner et de mailler le domaine sur lequel il est défini.Cette méthode est d'abord présentée pour les domaines simplement connexes, puis généralisée aux domaines non-simplement connexes. Elle nous permet de gérer les domaines constitués de plusieurs matériaux ainsi que les points singuliers de bord qui, en pratique, permettent de délimiter des portions de la frontière du domaine pour prendre en compte des conditions aux limites mixtes dans le cadre des simulations numériques. Enfin, nous mettons en place la discrétisation de la méthode sur des maillages triangulaires, puis nous proposons une généralisation à des surfaces courbes dans l'espace
The objective of this thesis is to provide new solutions to improve performance in the numerical solution of partial differential equations by studying a method for generating quadrilateral meshes based on cross-field techniques.Our approach relies on aligning a given cross field with the boundary of the computational domain, followed by partitioning the domain into four-sided regions which are then meshed into quadrilaterals. This allows us to generate a structured block mesh while preserving the positions of the singularities of the initial cross field. To achieve this, we conduct a theoretical study of cross fields to identify the conditions under which a given cross field effectively partitions and meshes the domain on which it is defined.This method is initially presented for simply connected domains and then extended to non-simply connected domains. It allows us to handle domains consisting of multiple materials as well as boundary singular points, which in practice delineate portions of the domain boundary to account for mixed boundary conditions in numerical simulations. Finally, we discretize the method on triangular meshes and propose a generalization to curved surfaces in space

Many real systems like the brain are considered to be complex, i.e. they are made of several interacting components and display a collective behaviour that cannot be inferred from how the individual parts behave. They are usually described as networks, with the components represented as nodes and the interactions between them as links. Research into networks mainly focuses on exploring how a network's dynamic behaviour is constrained by the nature and topology of the interactions between its elements. Analyses of this sort are performed on three scales: the microscale, based on single nodes; the macroscale, which explores the whole network; and the mesoscale, which studies groups of nodes. Nonetheless, most studies so far have focused on only one scale, despite increasing evidence suggesting that networks exhibit structure on several scales. In our thesis, we apply structural analysis to a variety of synthetic and empirical networks on multiple scales. We focus on the examination of nested, modular, and in-block nested patterns, and the effects that they impose on each other. Finally, we introduce a theoretical model to help us to better understand some of the mechanisms that enable such patterns to emerge.
Molts sistemes, com el cervell o internet, són considerats complexos: sistemes formats per una gran quantitat d'elements que interactuen entre si, que exhibeixen un comportament col·lectiu que no es pot inferir des de les propietats dels seus elements aïllats. Aquests sistemes s'estudien mitjançant xarxes, en les quals els elements constituents són els nodes, i les interaccions entre ells, els enllaços. La recerca en xarxes s'enfoca principalment a explorar com el comportament dinàmic d'una xarxa està definit per la naturalesa i la topologia de les interaccions entre els seus elements. Aquesta anàlisi sovint es fa en tres escales: la microescala, que estudia les propietats dels nodes individuals; la macroescala, que explora les propietats de tota la xarxa, i la mesoescala, basada en les propietats de grups de nodes. No obstant, la majoria dels estudis se centren només en una escala, tot i la creixent evidència que suggereix que les xarxes sovint exhibeixen estructura a múltiples escales. En aquesta tesi estudiarem les propietats estructurals de les xarxes a escala múltiple. Analitzarem les propietats estructurals dels patrons in-block nested i la seva relació amb els patrons niats i modulars. Finalment, introduirem un model teòric per explorar alguns dels mecanismes que permeten l'emergència d'aquests patrons.

Resumo:

A high-order central essentially non-oscillatory (CENO) finite-volume scheme in combination with a block-based adaptive mesh refinement (AMR) algorithm is proposed for solution of hyperbolic and elliptic systems of conservation laws on body- fitted multi-block mesh. The spatial discretization of the hyperbolic (inviscid) terms is based on a hybrid solution reconstruction procedure that combines an unlimited high-order k-exact least-squares reconstruction technique following from a fixed central stencil with a monotonicity preserving limited piecewise linear reconstruction algorithm. The limited reconstruction is applied to computational cells with under-resolved solution content and the unlimited k-exact reconstruction procedure is used for cells in which the solution is fully resolved. Switching in the hybrid procedure is determined by a solution smoothness indicator. The hybrid approach avoids the complexity associated with other ENO schemes that require reconstruction on multiple stencils and therefore, would seem very well suited for extension to unstructured meshes. The high-order elliptic (viscous) fluxes are computed based on a k-order accurate average gradient derived from a (k+1)-order accurate reconstruction. A novel h-refinement criterion based on the solution smoothness indicator is used to direct the steady and unsteady refinement of the AMR mesh. The predictive capabilities of the proposed high-order AMR scheme are demonstrated for the Euler and Navier-Stokes equations governing two-dimensional compressible gaseous flows as well as for advection-diffusion problems characterized by the full range of Peclet numbers, Pe. The ability of the scheme to accurately represent solutions with smooth extrema and yet robustly handle under-resolved and/or non-smooth solution content (i.e., shocks and other discontinuities) is shown for a range of problems. Moreover, the ability to perform mesh refinement in regions of smooth but under-resolved and/or non-smooth solution content to achieve the desired resolution is also demonstrated.

Taking South Africa as an important case study of the challenges of structural transformation, the book offers a new micro-meso level framework and evidence linking country-specific and global dynamics of change, with a focus on the current challenges and opportunities faced by middle-income countries. Detailed analyses of industry groupings and interests in South Africa reveal the complex set of interlocking country-specific factors which have hampered structural transformation over several decades, but also the emerging productive areas and opportunities for structural change. The structural transformation trajectory of South Africa presents a unique country case, given its industrial structure, concentration, and highly internationalized economy, as well as the objective of black economic empowerment. The book links these micro-meso dynamics to the global forces driving economic, institutional, and social change. These include digital industrialization, global value-chain consolidation, financialization, and environmental and other sustainability challenges which are reshaping structural transformation dynamics across middle-income countries like South Africa. While these new drivers of change are disrupting existing industries and interests in some areas, in others they are reinforcing existing trends and configurations of power. The book analyses the ways in which both the domestic and global drivers of structural transformation shape—and, in some cases, are shaped by—a country’s political settlement and its evolution. By focusing on the political economy of structural transformation, the book disentangles the specific dynamics underlying the South African experience of the middle-income country conundrum. In so doing, it brings to light the broader challenges faced by similar countries in achieving structural transformation via industrial policies.

Abstract Nearly everyone accepts as gospel two assumptions: compliance with environmental rules is good, and enforcement is responsible for making compliance happen. Both are wrong. In fact, serious violations of environmental regulations are widespread, and by far the most important driver of compliance results is not enforcement but the structure of the rule itself. In Next Generation Compliance: Environmental Regulation for the Modern Era, Cynthia Giles shows that well-designed regulations deploying creative strategies to make compliance the default can achieve excellent implementation outcomes. Poorly designed rules that create many opportunities to evade, obfuscate, or ignore will have dismal performance that no amount of enforcement will ever fix. Rampant violations have real consequences: unhealthy air, polluted water, contaminated drinking water, exposure to dangerous chemicals, and unrestrained climate-forcing pollution. They also land hardest on already overburdened communities—that’s why Next Gen and environmental justice are tightly linked. The good news is there are tools to build much better compliance into regulations, including many tested strategies that can be the building blocks of programs that withstand the inevitable pressures of real life. Next Generation Compliance shows how regulators can avoid the compliance calamities that plague far too many environmental rules today, a lesson that is particularly urgent for regulations tackling climate change. It has an optimistic message: there are ways to ensure reliable results, if regulators jettison incorrect assumptions and design rules that are resilient to the mess and complexity of the real world.

AbstractThis chapter provides insights into the intractable ethico-political nature of ‘access’ in post-colonial, post-conflict higher education (HE), through the reflections of Black academics and women academics who have lived experience of the minority-majority transitions of academic communities in post-apartheid South Africa. To address the lack of ‘diversity’ of under-represented demographics within historically white institutions, those institutions who provided access to these hand-picked academics did so requiring that they undergo rigorous professional development and socialisation programmes for the purposes of assuring their quality. Critical discourse analyses were undertaken of the qualitative responses of these academics made in response to a questionnaire on this subject, which were then confirmed and deepened within small group discussions. In this chapter we discuss how their responses revealed: (1) the mis-educational reception of structural access for troubling homogeneous institutional cultures; (2) the risks encountered in the politics of belonging of an individual’s access for success; and (3) the problematic weight of transformative expectations when conditions mitigate against empowering agents access to challenge. Situated within an historical narrative of academic development and the national drives in that country for an HE sector ‘transformed’ from its historical legacies of injustice and inequality, the chapter highlights the implications of these three constructions of access for disrupting the machinations of the hidden macro- and meso-curricula of power and whiteness.

Abstract The multiblock procedure (Shaw et al. 1988) has enjoyed considerable success in gridding many realistic aircraft configurations. In this approach, the grid is composed of a set of topologically hexahedral blocks, each containing a curvilinear mesh, and spatial block connectivities are described via a so-called block topology which can be determined automatically for target configurations. Within blocks, the mesh is determined as the solution of a set of elliptic PDEs whose source terms drive orthogonality at boundaries and mesh spacing in the field. C2 continuity is achieved across block interfaces.

Abstract The problem of predicting the flowfield around complex aircraft configurations continues to receive much interest within the aeronautical research community. To a great extent, the ability of a flow analysis method to examine increasingly complex geometries is paced by the mesh generation capability inherent to the method. In this respect, a number of different strategies have materialised over the past few years for discretising domains around complex configurations. One such strategy, and the one addressed here, is the structured/unstructured approach, whereby the flow-field is composed of regions of structured mesh (hexahedra) and regions of unstructured mesh (tetrahedra). As this approach has its origins in a much used block-structured (multi-block) method, Shaw et al. (1988), the hexahedral cells are contained within structured blocks. The background philosophy behind this approach to mesh generation is given in Shaw et al. (1990).

Abstract One of the main issues in grid generation is the improvement of the grid quality, both for structured and unstructured meshes. In the present work we focus our attention on the generation of structured grids. It is important to develop structured grid generation systems able to give “good” grids in topologically complex regions, because in this way it is possible to reduce the effort of block decomposition, with considerable improvement of the flow solver efficiency. By “good” meshes, we mean grids sufficiently smooth, and orthogonal along part of the boundary (for example along solid walls). Moreover, along the interior boundaries connecting different blocks, it is advisable to have the possibility of controlling both the grid point positions and the slope of the coordinate lines. The aim of this work is to present a mesh generation method for structured grids, able to solve the main issues pointed out above, specifically: a) smoothness, b) orthogonality control, c) specification of the grid point position and coordinate line slope along each boundary at the same time.

Resumo:

This paper presents a novel lattice Boltzmann (LB) model for neutron transfer and a block-structured adaptive-mesh-refinement (SAMR) technique for proposed LB model. By discretizing the general Boltzmann equation, the LB model for neutron transfer is established and the corresponding parameters are obtained. The SAMR technique removes the requirement of tree-type data structure in traditional adaptive-mesh-refinement technique and adjusts the time step adaptively and identically in all blocks. By applying the node-type distribution function, the needs for rescaling the distribution functions is eliminated. To solve the discontinuities of scalar flux at fine-coarse blocks interface, a novel technique is presented which treats the inner boundary condition by streaming process of LB method. Simulation results show good accuracy and efficiency of the proposed neutron LB model with SAMR technique. This paper may provide a powerful technique for large engineering calculation.

New geological mapping in the Tehery Lake-Wager Bay area of northwestern Hudson Bay, Nunavut, frames the emplacement, depositional, and metamorphic histories of the dominant rock types, major structures, and links to neighbouring areas of the central Rae Craton and Chesterfield Block. The area is divided into six domains (Ukkusiksalik, Douglas Harbour, Gordon, and Lunan domains presented here, and Kummel Lake Domain and Daly Bay Complex on adjoining maps) defined by large-scale structures and characterized by differing metamorphic assemblages, Sm-Nd and U-Pb isotopic data, and/or specific lithologies. Meso- to Neoarchean granitoid rocks underlie most of the area and are tectonically intercalated with Archean (volcano)sedimentary packages (Kummel Lake, Lorillard, and Paliak belts). These rocks are locally intruded by ca. 2.62 to 2.58 Ga Snow Island suite granite and cut by younger, thin, east-trending diabase dykes. Paleoproterozoic (volcano)sedimentary rocks are preserved in the Kingmirit belt (Daly Bay Complex) and in basement-cover infolds of Ketyet River group-equivalent strata (Douglas Harbour and Ukkusiksalik domains). In the south, the Daly Bay Complex (comprising mostly mafic granulite-facies rocks) and Kummel Lake Domain (a granulite-grade core complex) share some characteristics with rocks of the Kramanituar and Uvauk complexes, which may delineate the northeastern segment of the ca. 1.90 Ga Snowbird tectonic zone. The Paleoproterozoic Trans-Hudson Orogeny had widespread, penetrative structural and metamorphic effects on the area, and led to the intrusion of the ca. 1.85 to 1.81 Ga Hudson suite monzogranite and mafic ultrapotassic rocks, and ca. 1.83 Ga monzodiorite in the Ukkusiksalik and Douglas Harbour domains. The area is cut by large, southeast-trending gabbro dykes of the 1.267 Ga Mackenzie igneous event.
