The GETMe Mesh Smoothing Framework: A Geometric Way to Quality Finite Element Meshes
by Dimitris Vartziotis Joachim WipperHigh quality meshes play a key role in many applications based on digital modeling and simulation. The finite element method is a paragon for such an approach and it is well known that quality meshes can significantly improve computational efficiency and solution accuracy of this method. Therefore, a lot of effort has been put in methods for improving mesh quality. These range from simple geometric approaches, like Laplacian smoothing, with a high computational efficiency but possible low resulting mesh quality, to global optimization-based methods, resulting in an excellent mesh quality at the cost of an increased computational and implementational complexity. <P><P>The geometric element transformation method (GETMe) aims to fill the gap between these two approaches. It is based on geometric mesh element transformations, which iteratively transform polygonal and polyhedral elements into their regular counterparts or into elements with a prescribed shape. GETMe combines a Laplacian smoothing-like computational efficiency with a global optimization-like effectiveness. The method is straightforward to implement and its variants can also be used to improve tangled and anisotropic meshes. <P><P>This book describes the mathematical theory of geometric element transformations as foundation for mesh smoothing. It gives a thorough introduction to GETMe-based mesh smoothing and its algorithms providing a framework to focus on effectively improving key mesh quality aspects. It addresses the improvement of planar, surface, volumetric, mixed, isotropic, and anisotropic meshes and addresses aspects of combining mesh smoothing with topological mesh modification. <P><P>The advantages of GETMe-based mesh smoothing are demonstrated by the example of various numerical tests. These include smoothing of real world meshes from engineering applications as well as smoothing of synthetic meshes for demonstrating key aspects of GETMe-based mesh improvement. Results are compared with those of other smoothing methods in terms of runtime behavior, mesh quality, and resulting finite element solution efficiency and accuracy. <P><P>Features: <li>Helps to improve finite element mesh quality by applying geometry-driven mesh smoothing approaches. <li>Supports the reader in understanding and implementing GETMe-based mesh smoothing. <li>Discusses aspects and properties of GETMe smoothing variants and thus provides guidance for choosing the appropriate mesh improvement algorithm. <li>Addresses smoothing of various mesh types: planar, surface, volumetric, isotropic, anisotropic, non-mixed, and mixed. <li>Provides and analyzes geometric element transformations for polygonal and polyhedral elements with regular and non-regular limits. <li>Includes a broad range of numerical examples and compares results with those of other smoothing methods.
Getriebekonzepte für Fahrzeuge: Übertragungskonzepte für Fahrzeugantriebe – heute und zukünftig (erfolgreich studieren)
by Werner KlementAuf Grundlage von Konzeptfahrzeugen werden die spezifischen Anforderungen an Getriebe je nach Antriebskonzept erarbeitet und die technischen Möglichkeiten aufgezeigt. Dabei werden zunächst grundlegende Aspekte wie der Leistungsfluss abgeleitet und anhand praktischer Beispiele verdeutlicht. Es werden Lösungen sowohl für Verbrennungsmotoren in PKW als auch für LKW beschrieben. Im Bereich der Ackerschlepper spielen stufenlose Getriebekonzepte eine bedeutende Rolle. Bei alternativen Fahrzeugantrieben werden die Möglichkeiten von Hybridlösungen sowie die Notwendigkeit einer geeigneten Übersetzung für elektrische Antriebe behandelt. Der Fokus liegt dabei stets auf der Fahrzeuganwendung und den daraus resultierenden Anforderungen an die Übertragungskomponenten bei gegebener Energiequelle. Getriebe sind keine eigenständigen Produkte, sondern fungieren als „Übersetzer“, die passgenau die Anforderungen des jeweiligen Fahrzeugs erfüllen müssen. Oft ergibt sich daraus eine ganzheitliche Lösung, die in Bezug auf Performance und Wirkungsgrad Standardanwendungen überlegen ist. Zahlreiche Beispiele verdeutlichen diese Symbiose und die damit einhergehende Verbesserung der Gesamtsysteme.

Getting Started with CNC: Personal Digital Fabrication with Shapeoko and Other Computer-Controlled Routers
by Edward FordGetting Started with CNC is the definitive introduction to working with affordable desktop and benchtop CNCs, written by the creator of the popular open hardware CNC, the Shapeoko. Accessible 3D printing introduced the masses to computer-controlled additive fabrication. But the flip side of that is subtractive fabrication: instead of adding material to create a shape like a 3D printer does, a CNC starts with a solid piece of material and takes away from it. Although inexpensive 3D printers can make great things with plastic, a CNC can carve highly durable pieces out of a block of aluminum, wood, and other materials. This book covers the fundamentals of designing for--and working with--affordable ($500-$3000) CNCs.
