Caedium v4 Sneak Peek: Idealized Dyson Air Multiplier CFD Simulation

Progress on the next Caedium (v4) release is gaining steam, so it's high time for a sneak peek at some of the new capabilities. As you'll see, an idealized Dyson Air Multiplier Computational Fluid Dynamics (CFD) simulation proved to be an excellent test case.

How to Lose F1 Races with a Wind Tunnel and CFD

I recently came across a blog post "How to lose races with CFD" [source: Another Fine Mesh] related to the CFD-only strategy pursued by the Marussia Formula 1 Team (formerly Virgin Racing) during the 2010 and 2011 F1 seasons. It seems such an easy conclusion to make, right? During its first 2 F1 seasons the Marussia team garnered a lot of publicity thanks to their CFD-only (no wind tunnel testing) strategy and during that period they didn't win a race, therefore CFD must lose races, right? Not so fast.

What's Holding Back Computational Fluid Dynamics?

The results are in for our latest poll and from 166 visitors to the Symscape website an overwhelmingly number (49%) cited the price of Computational Fluid Dynamics (CFD) software as the biggest barrier to further CFD adoption. The second most cited concern (17%) was CFD software complexity.

Flying Humans Spotted Over New York

Yes you read that right - three humans were recently spotted flying over New York without a jetpack in sight. Don't believe me? Then watch this video:

Puddle: Another Fluid Game

Do you sometimes feel like your Computational Fluid Dynamics (CFD) simulation just needs a little nudge to do the right thing? Well I'm sure you'll appreciate (need even!) some light relief with the fluid-based video game Puddle. Puddle is all about nudging and manipulating the world so your precious fluid gets to its destination through a fiendish puzzle-like maze.

Fluid Wrist Watch for a Fluid Dynamicist

Any fluid dynamicists out there searching for just the right wrist watch? Well the search is over, check out the HYT H1 [source: Gizmodo] fluid-themed watch from "The Hydro Mechanical Horologists" - try saying that after too much fluid!

An Update on HPC's Missing Middle

The report "Council on Competitiveness and USC-ISI Broad Study of Desktop Technical Computing End Users and HPC" [pdf] by the Council on Competitiveness and sponsored by DARPA in 2008 found that a large number of companies deployed virtual prototyping and data modeling software (e.g., Computational Fluid Dynamics [CFD]) on entry level High Performance Computing (HPC) or desktop computers as opposed to realizing the performance and fidelity gains available with true HPC systems. In a subsequent follow up report [pdf] the authors coined the phrase 'the missing middle' to describe the gap in HPC usage.

RC Car Integrates Advanced Aerodynamics Package

Going fast and aerodynamics are intimately related, whether it's for a Formula 1 car or in this case for a remote control (RC) car. The Traxxas XO-1 is billed as "The World's Fastest Ready-To-Race Supercar" with a 0-100 mph time of under 5 seconds. More interesting than its out-and-out straight-line speed is that this RC car employs advanced aerodynamics for generating downforce.

CFD Study Confirms Fabric Ducts Are More Efficient Than Metal Ducts

An extensive Computational Fluid Dynamics (CFD) study [pdf] performed over 10 months by a team at Iowa State University [source: green building pro] confirmed what many room occupants long suspected - that fabric ducts offer better indoor air comfort compared to traditional metal ducts. Equally impressive, the study found that the fabric ducts provided a 22-27% improvement in energy efficiency compared to equivalent metal ducts.
