We’re all familiar with the legendary Concorde that enabled supersonic transcontinental travel, cutting down on travel time across the Atlantic to under 3.5 hours. The sonic boom of the Concorde was the primary reason why it was only used for flights over the ocean, instead of over-the-land travel. Decades later, NASA’s X-59 Quesst (Quiet SuperSonic

When a beam is loaded, the effect is not limited to the visible external forces. Internally, the structure develops reaction forces, shear forces, and bending moments that vary continuously along its length. If an engineer wants to know where stresses will be highest, where yielding may begin, or whether an FEA result is physically reasonable,

Have you ever had a design that “looked fine” by stress… until a tiny crack (or a sharp corner, inclusion, weld toe, pore, or delamination) decided otherwise? Then you’ve already met the reason fracture mechanics exists. In short, fracture mechanics is about characterizing the crack-tip driving force (energy release rate / stress intensity) and comparing

Fidelis Industry Insights is a series focused on where modern simulation—and the SIMULIA toolset behind it—can materially change how engineering teams design, verify, and deliver products. This installment is about the medical industry: implants, surgical tools, drug-delivery devices, diagnostics, and medical electrical equipment where the cost of late surprises is high and the tolerance for

Fidelis Industry Insights is a series of posts focused on where Fidelis—and the industry-leading SIMULIA software we provide—can change the way teams approach engineering problems. In this installment, we’re looking at pressure vessels and how finite element analysis (FEA) supports decisions across the full lifecycle: from initial design to fitness for service (FFS) once the

Fidelis has worked hand in hand with PEs since it’s inception back in 2019. We’ve gone above and beyond to provide on-demand engineering simulation solutions to PEs that just don’t have the capability or capacity that they require and, in turn, our PE partners have provided stamp and seal services where we are not covered

Simulation-driven design isn’t just for big metal structures anymore. Printed circuit boards (PCBs) are now carrying higher power densities, more delicate packages, and tighter allowable margins on reliability. As a result, thermal and dynamic (vibration/shock) substantiation of boards has become a first-class engineering task rather than an afterthought. What Is PCB Thermal & Vibration Analysis?

In electromagnetic simulations performed in specialized tools such as CST Studio Suite, a port is a defined interface through which electromagnetic energy enters or exits the system. It serves as a connection point between the device and the external environment, enabling the excitation of the model or the measurement of its response. Ports represent the

Electromagnetic (EM) simulation involves using computational models to predict how electric and magnetic fields interact with various materials, components, and structures by solving Maxwell’s equations. Instead of relying on physical prototypes, we can employ these simulations to analyze and visualize how electromagnetic waves propagate and behave in complex environments. This approach streamlines the design and
