Multibody Dynamics, Thermo-Fluid Optimization & 12 Steps to Navier-Stokes
🧠 “Some fear flutter because they do not understand it. And some fear it because they do.” – Theodore von Karman
💻 Simulating Reality with Simscape: Multi-Body Dynamics & AI – Steve Miller | Podcast #152
🎙️ In this episode of the Engineered-Mind Podcast, I speak with Steve Miller, Product Manager at MathWorks, about how multi-body dynamics models real-world mechanical systems with high fidelity. We cover how tools like Simscape Multibody allow engineers to simulate everything from suspensions and power steering to robots and heavy machinery, while integrating with electrical, hydraulic, and control systems.
🚀 Thermo-fluid optimization for space applications
Join Fine Physics and ToffeeX for a webinar on next-generation thermal management design, with a focus on space applications.
Optimization of heat exchange and cooling technology has evolved through various techniques, including Design of Experiments (DOE), parametric optimization, and surrogate modeling. While each method has brought advancements, they’ve also faced limitations—ranging from constraints on parameter complexity to the need for extensive training data.

💨 Aircraft Vortex Generators – The Nacelle Strakes
In modern transport aircraft, underwing engine nacelle installation is the most common design choice. Here, the engine nacelles which are tightly coupled with the wing have a huge impact on the maximum lift and stall angle of the wing. With the usage of larger by-pass ratio engines over the years, the adverse effects of the nacelle on the wing’s performance have increased dramatically, especially so when the high lift devices are deployed.
MIT | Finite Element Procedures for Solids and Structures, Linear Analysis
Finite element analysis is now widely used for solving complex static and dynamic problems encountered in engineering and the sciences. In these two video courses, Professor K. J. Bathe, a researcher of world renown in the field of finite element analysis, teaches the basic principles used for effective finite element analysis, describes the general assumptions, and discusses the implementation of finite element procedures for linear and nonlinear analyses.
These videos were produced in 1982 and 1986 by the MIT Center for Advanced Engineering Study.
💦 CFD Python: 12 steps to Navier-Stokes
CFD Python, a.k.a. the 12 steps to Navier-Stokes, is a practical module for learning the foundations of Computational Fluid Dynamics (CFD) by coding solutions to the basic partial differential equations that describe the physics of fluid flow. The module was part of a course taught by Prof. Lorena Barba between 2009 and 2013 in the Mechanical Engineering department at Boston University (Prof. Barba since moved to the George Washington University).

💻 Engineering Tool of the Week – Sparselizard
Sparselizard is a high-performance, multiphysics, hp-adaptive, open source C++ finite element library running on Linux, Mac and Windows. A fast algorithm for mesh-to-mesh interpolation and a general implementation of the mortar finite element method allow to easily work with non-matching meshes and provide general periodic conditions. FEM simulations can be weakly or strongly coupled to lumped electric circuits.
Sparselizard can handle a general set of problems in 3D, 2D axisymmetric, 2D and 1D such as mechanical (anisotropic elasticity, geometric nonlinearity, buckling, contact, crystal orientation), fluid flow (laminar, creeping, incompressible, compressible), stabilized advection-diffusion, nonlinear acoustic, thermal, thermoacoustic, fluid-structure interaction, electric, magnetic, electromagnetic, piezoelectric, superconductor,... problems with a transient, (multi)harmonic or damped/undamped eigenmode analysis.
📚Book of the Week
Practical Finite Element Analysis for Mechanical Engineers
"Practical Finite Element Analysis for Mechanical Engineers" is a book about the practical aspect of finite element analysis for structural engineers.
The objective is to offer the best practical methods and guidelines for the development and validation of finite element models.
It gives to the structural engineers the keys to developing accurate and reliable finite element models by avoiding the most frequent errors. It contains around 100 examples that illustrate the different modelling techniques.
