Expecting The Unexpected: Analyzing A Data Center Cooling Failure
By Mark Seymour - 15 Feb, 2024 - Comments: 0

Data center thermal management is often a reactive process. Servers issue warning messages, monitoring alarms activate, or employees express concern about general temperature levels/hotspots and then management decides what to do next. For incremental issues, once known, the necessary steps can be taken to resolve or improve these issues; however, what happens when a potential thermal issue onl... » read more

Fuel Economy And Aerodynamics: The Yin And Yang Of Car Design
By Veena Parthan - 01 Feb, 2024 - Comments: 0

From the classic Model T to the iconic American muscle cars, the design of cars has been shaped by many factors over the years. Technological advancements, consumer preferences, and government regulations have all played their part. But one factor that has been a game changer is fuel efficiency. The Corporate Average Fuel Economy (CAFE) standards, introduced in the aftermath of the 1973 oil em... » read more

Can Data Centers Afford To Turn Up The Heat?
By Mark Seymour - 25 Jan, 2024 - Comments: 0

Typically, when we discuss digital twin software for data centers, we highlight how engineers can use data center software to model complex thermals using physics-based simulation and find effective ways to cool IT equipment. However, there are compelling efficiency and cost-saving reasons for data center operators to actively seek to run their data centers hotter. But how can this be done wit... » read more

Understand The Physics Of Re-Entry Vehicles Using Numerical Modeling And Simulation
By Veena Parthan - 12 Oct, 2023 - Comments: 0

In the early years of space exploration, scientists and engineers dreamed of sending vehicles to Mars that could land on the planet's surface and explore its terrain. However, one of their biggest challenges was safely reentering the Martian atmosphere. Many early attempts at Mars missions failed because the vehicles either burned up during re-entry or crashed onto the surface. However, as tech... » read more

Cleaning Marine Geometries Has Never Been Easier
By Veena Parthan - 10 Aug, 2023 - Comments: 0

Ship designers and naval architects increasingly use computational fluid dynamics (CFD) tools for more accurate solutions, detailed physics, and quicker results. Marine ship design studies in the past relied mainly on scaled-down models in towing tanks for insights into ship resistance, seakeeping, propulsion, and maneuvering. However, these models had discrepancies in their Reynolds and Fro... » read more

Boost Your CFD Workflow Productivity With An API: Part 1
By Veena Parthan - 03 Aug, 2023 - Comments: 0

If you're in the field of computational fluid dynamics testing or studies, you already know how much time and effort it takes to complete the tasks involved. Hours upon hours are spent on geometry clean-up, meshing, and post-processing. Furthermore, when you're dealing with similar models that have new constraints or dimensions, the work can feel tedious. But don't worry! There’s a way to sim... » read more

Reduce Aquaculture Biological Footprint With Fluid-Structure Interaction Simulations
By Veena Parthan - 06 Jul, 2023 - Comments: 0

Aquaculture, which has existed since 1000 BCE, is gaining widespread recognition for its potential to provide sustainable fish products. This form of farming, also known as captive breeding, is the go-to method for fish farmers to satisfy the growing demand for seafood and freshwater fish. In aquaculture farming, choosing the right location is substantial for healthy breeding, such as having co... » read more

Balancing AI And Engineering Expertise In The Fab
By Laura Peters - 28 Jun, 2023 - Comments: 1

Modeling and simulation are playing increasingly critical roles in chip development due to tighter process specs, shrinking process windows, and fierce competition to bring technologies to market first. Before a new device makes it to high-volume manufacturing, there are countless engineering hours spent on developing the lithography, etching, deposition, CMP, and many other processes, at hi... » read more

High-Fidelity CFD Mesh Generation With Voronoi Diagram
By Veena Parthan - 11 May, 2023 - Comments: 0

We are attuned to the fact that the law of nature, or nature’s rule, drives various scientific phenomena. Humans often replicate naturally occurring phenomena to achieve a desirable outcome, similar to how scientists mimic photosynthesis to generate energy. Comparable is the case with Voronoi geometries. These geometries are widely seen in beehives, the structure of sponges, rock fragmentati... » read more
