The Lattice Boltmann Method, Validation in FEM & Turbulence Phenomena
🔩 "Engineering is the art and science of nuts and bolts.” – Haresh Sippy
💻 Model-Based Design & AI in Engineering
Model-Based Design is the systematic use of models throughout the development process that improves how you deliver complex systems. You can use Model-Based Design with MATLAB and Simulink to shorten development cycles and reduce your development time by 50% or more.
🎙️Podcast – The Lattice Boltzmann Method
Based on his fascination for GPU and 3D graphics, Eugen initiated the development of a prototypical GPU-accelerated program for simulating flows as early as 2007 during his studies in aerospace at the Technical University of Munich (TUM).
Following his studies, he brought the software prototype into an existing spin-off company, which he had previously helped to build through his expertise in HPC and GPU. With the experience he gained, he started his own business in 2013 to develop pacefish® to market maturity as a highly efficient tool for simulating fluid flows. In 2016, he then founded Numeric Systems GmbH.
💻 Validation and Insight Using Ansys Mechanical
Reviewing the calculated results is the most critical part of any simulation. Evaluating deformation and stresses is a primary objective of our analysis, and we may need to determine our engineered design’s safety factors. However, postprocessing also helps us verify that our model setup was correct and that we don't have unexpected behaviors we can't account for. Moreover, we can compare results from different designs to evaluate the optimal configuration.
🌀 Turbulence: Finding Order in Chaos
It defines the shape of the cars we drive and the planes we fly on, yet it remains largely invisible. You can see it in the plume of a cigarette or your breath on a cold morning. Turbulence is all around of us but for many the word turbulence is largely associated with a bumpy flight. Neil will introduce you to the chaotic side of nature that remains one of physics greatest unsolved mysteries.
Dr. Neil Ashton discusses how our understanding of turbulence is enabling us to unravel some of the mysteries of nature. We learn how the flipper of a humpback whale inspired the look of one of the latest F1 cars, and why golf balls have dimples. By using some of the biggest supercomputers in the world, our knowledge of turbulence is bringing a new era of discovery.
🤓 Eighty Years of the Finite Element Method: Birth, Evolution, and Future
This document presents comprehensive historical accounts on the developments of fnite element methods (FEM) since 1941, with a specifc emphasis on developments related to solid mechanics. We present a historical overview beginning with the theoretical formulations and origins of the FEM, while discussing important developments that have enabled the FEM to become the numerical method of choice for so many problems rooted in solid mechanics.
💻 Engineering Tool of the Week – GIBBON
GIBBON (The Geometry and Image-Based Bioengineering add-On) is an open-source MATLAB toolbox by Kevin M. Moerman and includes an array of image and geometry visualization and processing tools and is interfaced with free open source software such as TetGen, for robust tetrahedral meshing, and FEBio for finite element analysis. The combination provides a highly flexible image-based modelling environment and enables advanced inverse finite element analysis.
📚Book of the Week
The Finite Volume Method in Computational Fluid Dynamics
This textbook explores both the theoretical foundation of the Finite Volume Method (FVM) and its applications in Computational Fluid Dynamics (CFD). Readers will discover a thorough explanation of the FVM numerics and algorithms used for the simulation of incompressible and compressible fluid flows, along with a detailed examination of the components needed for the development of a collocated unstructured pressure-based CFD solver. Two particular CFD codes are explored. The first is uFVM, a three-dimensional unstructured pressure-based finite volume academic CFD code, implemented within Matlab. The second is OpenFOAM®, an open source framework used in the development of a range of CFD programs for the simulation of industrial scale flow problems.
With over 220 figures, numerous examples and more than one hundred exercise on FVM numerics, programming, and applications, this textbook is suitable for use in an introductory course on the FVM, in an advanced course on numerics, and as a reference for CFD programmers and researchers.-
