๐ย The Finite Element Method (FEM) โ A Beginner's Guide
Get a simple introduction to the Finite Element Method (FEM), how a Finite Element Analysis (FEA) workflow looks like and how it is used in the industry.
๐ย MIT Finite Element Procedures for Solids and Structures, Linear Analysis
Excellent MIT class on FEM by instructor and FEM legend Klaus-Juฬrgen Bathe.
๐ Noise cancelation gone too far!
Getting rid of the side-view mirrors is an aggressive but effective solution to the problem of decreasing its induced aeroacoustics sound, especially more prominent in our vehicle fleet becoming quieter through electrificationโฆ
Learn about side mirrors aeroacoustics CFD predictions in this great Siemens article.
๐ฆย The Navier-Stokes Equations
In 1845, Sir George Stokes had derived the equation of motion of a viscous flow by adding Newtonian viscous terms, thereby the Navier-Stokes Equations had been brought to their final form which has been used to generate numerical solutions for fluid flow ever since.
In this equation, the formula forย mass continuityย is missing and other assumptions go into this equation. You can find the full derivation of the equationย here.

โจ๏ธ The Schlieren Method
Schlieren imaging systems have been used since the early 1800โs to visualize fluctuations in optical density. As a dynamic and straightforward visualization tool, these systems are primarily applied to conduct qualitative visual studies.
Schlieren optics provide an informative, non-intrusive method for studying transparent and optical media. It is beneficial to use them in fluid dynamics studies because they are sensitive to changes and do not interfere with flow. They are also used to study optical media and changes in refractive index within the material. Most commonly, schlieren systems have been applied to visualize diverse subjects such as striations in blown glass, inhalation in humans and animals, shock waves from a plane in flight, and heat emanating from a system.ย Source

๐ป Engineering Tool of the Week - SfePy: Simple Finite Elements in Python
SfePy is a software for solving systems of coupled partial differential equations (PDEs) by the finite element method in 1D, 2D and 3D. It can be viewed both as black-box PDE solver, and as a Python package which can be used for building custom applications. The word โsimpleโ means that complex FEM problems can be coded very easily and rapidly.
๐Book of the Week
Notes on Computational Fluid Dynamics: General Principles
Notes on Computational Fluid Dynamics (CFD) was written for people who use CFD in their work, research or study, providing essential knowledge to perform CFD analysis with confidence. It offers a modern perspective on CFD with the finite volume method, as implemented in OpenFOAM and other popular general-purpose CFD software.
Fluid dynamics, turbulence modelling and boundary conditions are presented alongside the numerical methods and algorithms in a series of short, digestible topics, or notes, that contain complete, concise and relevant information. The book benefits from the experience of the authors: Henry Weller, core developer of OpenFOAM since writing its first lines in 1989; and, Chris Greenshields, who has delivered over 650 days of CFD training with OpenFOAM.
