I have often said that geometry modeling is to mesh generation what turbulence modeling is to CFD: a huge challenge. In the interview below, Cadence's Nick Wyman discusses the scope of this challenge with Engineering.com. You can read the full ar...

Want to see it in action? REGISTER FOR WEBINAR The newest version of the Omnis simulation environment brings a new discrete particle solver, a surface-to-volume mesh module and more than 100 other new features that will simpli...

It's a short week here at Cadence CFD as we celebrate the Juneteenth holiday today. But CFD doesn't take time off as evidenced by the latest round-up of CFD news. There are several really cool CFD applications profiled this week including a m...

In June once more we launch a series of not-to-miss live webinars on various CFD topics. It's a great opportunity to learn about the latest advancements in CFD simulation, see our tools in action first-hand and ask any questions you may have str...

I hope you didn't think I had forgotten. But last Friday was a tad busy so I didn't have a chance to share This Week in CFD here. So let's start the week with some CFD news and some good news at that. A lot of financials have been reporte...

As the title says, Pointwise Version 18.4 R4 is now available for download and production use. V18.4 R4 consists almost entirely of bug fixes. The only new feature is extension of the Glyph scripting command getCellsUsingIndex to surface meshes. (It ...

The return to supersonic flight is amongst the hottest topics in aviation today, as several companies (Boom Supersonic and Aerion, among others) are actively developing new supersonic commercial airliners targeted to enter in service in the comi...

Today's not just Tuesday, it's Tutorial Tuesday. What's that, you ask? Each Tuesday for what seems like forever, we've been publishing a new video on Pointwise's YouTube channel. And these aren't just any videos. They help you...

This week’s CFD news includes both an image of the week and an application of the week – draw your own conclusions. We’re still seeing a lot of online events but I am happy that AIAA SciTech 2022 looks to be an online and in-person ...

In the beginning there was the airfoil. Or more specifically, in 1968 it became clear that something new was needed to help design supercritical airfoils and wings. Today there is serious planning for aircraft certification by simulation and for main...

Drones have proven to be an efficient solution for a large range of applications within the military, industrial, and private consumer domains. In the past decade, their use has been soaring and their annual growth rate is anticipated to exceed 50%.....

Another Friday, another week chock full of CFD, CAE, and CAD news. This week features a topic near and dear to my heart involving death of the rainbow color map for displaying simulation results. There are a couple of good "list" articles o...

It's Friday which means it's time for that weekly roundup of news from the CFD world including industry announcements, event updates, cool applications, and more. This week finds an uptick in hypersonic and built-environment applicatio...

For the third time*, I find myself writing the obligatory, "Hello, World!" first blog post. So "Hello" to all you readers of Cadence's Computational Fluid Dynamics blog. (Or as someone else put it, Cadence Fluid Dynamics.) Who...

Here's a video titled Thermal Analysis of a Hardware Blade System. The "blade system" is Cadence's Protium FPGA prototyping system. Not the X2 that we announced a few weeks ago, but the X1. The thermal analysis is done using Cadence's Celsius tool. Y...

This week’s compilation of CFD news begins with a must-read article on how to choose colors properly when visualizing data. AI comes up twice this week as does Fortran which makes one wonder whether anyone’s programming AI in Fortran. The...

This Week in CFD reached convergence long before I had exhausted the two-week backlog of news. With baseball season underway here in the US, fans will enjoy the case study describing how high-fidelity CFD can predict the trajectory of various types o...

AeroDelft is a student team at the forefront of sustainable aviation. While based in Delft, over forty students from different schools and universities around the Netherlands have joined together and are working hard to push the airline industry tow...

It’s a good Friday for the latest roundup of CFD flotsam and jetsam from the ocean that is the internet. [Making this the Great CFD Garbage Gyre?] We use the marine theme because, for unexplained reasons, there are a lot of marine applications ...

All things being equal, CFD practitioners prefer to use hexahedral mesh cells in the boundary layer for the improved robustness and accuracy they bring to the flow solver. Traditionally, a hex grid would be created using a structured grid technique (...

Once again Emirates Team New Zealand has entered the history books and won the America’s Cup for New Zealand for the fourth time. After four years of planning and development, 170 years of Cup history, the last races of this 36th edi...

Petrochemical and other industrial applications rely on fans for a series of gas handling processes - which can range anywhere from ambient air ventilation to harmful chloride gases above 500C. The maximum operation speed of these fans is governed a...
