In our previous blog, we described the turbulent energy cascade and the turbulent energy spectrum that characterizes a turbulent flow. To summarize, a turbulent flow consists of eddies (swirling regions of fluid) of different sizes. These eddies range from being a comparable size to the characteristic length of the system and being heavily geometry dependent,

One way to significantly reduce the size of an FEA job is to utilize symmetry. But how do we do it, and when can we apply symmetry? We’ll go over all that in this blog, as well as the cases of antisymmetry, asymmetry, and axisymmetry! When Can I Use Symmetry? When using the term symmetry

The popularity of CFD for industrial applications, as well as academic research to accurately predict fluid flow behavior, is ever increasing as technological advances are made in computing technology and speed (e.g., massively parallel supercomputers with GPU acceleration). Within the heart of these CFD simulations, two main methodologies exist: the Navier-Stokes approach and the Lattice

Before we dive deeper into turbulence modelling in CFD, it is crucial to understand the different scales of turbulence and the energy cascade. Let’s look at a brief overview of the energy cascade and the turbulent energy spectrum. The Scales of Turbulence A turbulent flow consists of eddies, which are swirling regions of fluid motion

Fluids are all around us, including the air we breathe, the water we drink, and the blood flowing in our body. Understanding how fluids interact with our surroundings allows us to harness their potential for endless applications in multiple disciplines. For example, reducing the air resistance/drag on cars and airplanes so we can travel faster

Introduction Shock Response Spectrum (SRS) analysis is used to calculate the peak response of a physical system subjected to shock loads in the frequency domain. This is a very useful, inexpensive tool that provides qualitative comparisons between preliminary designs. It is often essential in the fields of engineering, material science, and electronics where rapid transient

Bolts are one of the most common ways to connect parts together. They have a high strength capacity and they are great to use when disassembly is necessary. It is important to correctly model these when performing FEA, but the modeling approach can vary quite a bit. In this blog, we’ll examine four different levels

Heat transfer is a huge factor to consider in so many industries, including propulsion, electronics, manufacturing, and HVAC. There are three modes by which this can happen – conduction, convection, and radiation. In this blog, we will go through the basics of these modes and how we can implement them in Abaqus CAE. Conduction Conduction

Safety factors are very common in engineering design to reduce the risk of product failure. However, there are a many different ways to apply them as well as to report them. In this blog, we’ll explore these and clear up, once and for all, the differences between ‘safety factor’, ‘factor of safety’, ‘margin of safety’

Isaac Newton defines inertia as the tendency of objects in motion to stay in motion, and objects at rest to stay at rest, unless an outside force changes its speed or direction. However, if you’ve been in the realm of mechanical design for any length of time, you’ll likely have heard the term “moment of
