Last Week at Fidelity CFD

Wow. By all accounts, CadenceCONNECT CFD and CadenceLIVE Silicon Valley last week were great events. We had a super line-up of speakers including a keynote from McLaren (hope you got to see their car and experience their simulator in the Designer Expo), Lockheed Martin, Hopium, Honeywell, Concepts NREC, and more. You'll probably be hearing more about what was discussed in the coming weeks as we share news online for those who could not attend. And now, let's check what else the Fidelity CFD team has been up to.

From the Blogs

There have been a lot of great blog posts since the last time we published Last Week at Fidelity CFD. So hang on.

Efficiency in Combustion, Efficiency in Computation - A Match Made in GPU Heaven

A lot has changed in the CFD world since the early 1980s. Today we have software like CharLES from Cadence's recent acquisition of Cascade Technologies that can accurately compute a transient flowfield with combustion and large eddy simulation of turbulence. Check out this video of the solution, and be mesmerized. Read more.

GPU Accelerated Cadence CFD Solutions at NVIDIA GTC 2023

As we witness a surge in the need for computational resources accompanied by skyrocketing data center power, it becomes difficult for organizations to comply with and achieve net-zero targets. However, these challenges can be tackled with powerful tools such as accelerated computing and AI. NVIDIA GTC 2023 was all about the new chips and systems, acceleration libraries, cloud and AI services, and partnerships that open new markets. Read more.

I’m Peter Weitzman and This Is How I Mesh

Hi, I’m Peter Weitzman, and I’m the president of Agile Engineering Software at Concepts NREC. I lead a team of software developers, application engineers, product managers, and salespeople who develop, sell and support specialized software for the design and manufacturing of turbomachinery. I have been doing this job for the past eight years. We have two major software product lines: CAE (computer-aided engineering) and CAM (computer-aided manufacturing). The CAE software is a complete design suite for turbomachinery that starts with the thermodynamic cycle and goes all the way to detailed 3D design, including 3D CFD and FEA. Read more.

Predicting Hull Resistance Curve Using Fidelity FINE Marine

In this user case, Marintek uses Fidelity Fine/Marine and Hexpress for resistance curve prediction of a planning hull and its validation against the model test cases. Read more.

The Handiest CFD App - The Y+ Calculator

The Y+ Calculator app is a handy tool for calculating the grid spacing to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations. Simply specify the flow conditions, the desired y+ value, and compute your grid spacing. Read more.

You simply MUST download the Y+ Calculator for your mobile device.

Mesh Resolution: Bringing Order to Coarse, Medium, Fine

The 3rd AIAA CFD High Lift Prediction Workshop (HiLiftPW-3) was largely a grid convergence study with mesh resolution levels defined primarily by guidelines for wall spacing, the number of mesh points across a blunt trailing edge, and a factor of three in total mesh size between resolution levels. Those levels were named coarse, medium, fine, and extra fine. The medium resolution mesh was generally defined as the mesh you'd use in your normal work. Read more.

Glyph API for Python in Fidelity Pointwise

Ever wish you could write Glyph scripts to extend or customize the functionality of Cadence's Fidelity Pointwise software in some language other than Tcl/Tk? Python coders: wish no more! In conjunction with the release of Pointwise V18.2 in September 2018, we've developed and published a wrapper API that provides full access to Glyph commands in a very Python-ic way that is still very familiar to the Tcl/Tk script writer. To a Python coder, the interface looks and feels like native Python, with the clear advantage of being able to use the full power of any community-developed Python package. Read more.

Accuracy, Convergence, and Mesh Quality

“We know embarrassingly little about how the mesh affects the CFD solution,” said Prof. Carl Ollivier-Gooch of the University of British Columbia. That statement is counter to what we all know to be true in practice, that a good mesh helps the computational fluid dynamics (CFD) solver converge to the correct answer while minimizing the computer resources expended. Stated differently, most every decent solver will yield an accurate answer with a good mesh, but it takes the most robust of solvers to get any answer on a bad mesh. Read more.

Printing Grids in 3D

Those of you who attended the 2011 Pointwise User Group Meeting may remember that our company president, John Chawner, mentioned during his closing statements how nice it would be to have the ability to print your grids in 3D. That was more than just a dreamy, "what if" statement. It is a reality! Read more.

Leverage CFD to Predict, Model, and Mitigate Tsunamis for a Safer Tomorrow

Severe heatwaves, frequent droughts, floods, melting ice caps, and warm oceans with acidic waters are all signs of climate change and its drastic impact. It’s not our planet’s first time; Earth has experienced these glacial and inter-glacial periods every 100,000-year cycle in the last 1 million years. So, we rest assured that Earth will survive, and evolutionary changes will follow, but what qualms us is that climate change might wipe off mankind and disturb the ecosystem. Predicting and modeling a few outcomes of climate change using advanced simulation tools can be a positive stride against climate change. Here we elaborate on how computational fluid dynamic (CFD) tools can help predict and model the generation, propagation, and mitigation of tsunamis for a safer tomorrow, especially targeting the safety of the inhabitants and building clusters around the coastal regions.

Damen Is Building Ships and Making Waves with Cadence CFD and Cloud Solutions

Damen is an international shipbuilding group with more than 50 shipyards in over 120 countries. While bare hull resistance simulations have been their bread and butter for a long time, they’re now looking at more complex simulations such as propulsion and maneuvering. With the help of Cadence’s CFD and cloud solutions, they’re now carrying out CFD simulations throughout the design workflow instead of just the late stages. Watch now.

Hermeus Is Reaching for Mach 5 with Cadence’s Fidelity Pointwise and Fidelity CFD Solutions
