Hopefully you were suitably inspired by "CFD Novice to Expert Part 1: Get Inspired" and that's why you are here now ready for part 2 of this 7-part series.

CFD Novice to Expert Part 1: Get Inspired

Say you've come up with an idea that can solve the energy crisis by reducing the drag of cars by X%, but how to proceed? Whichever way you turn you keep coming across the same phrase - Computational Fluid Dynamics (CFD) - with the almost fantastical claim that it can, in large part, replace expensive physical modeling techniques such as wind tunnels - but still, how to proceed? Money and time are tight, but you're talking about solving the energy crisis for the good of humanity. There simply has to be a way to proceed. Enough already - let's proceed with part 1 of this 7-part series.

April Fools - Caedium is not on the iPad

You probably guessed that yesterday was April Fools' Day and in the spirit of fake news we announced that our unified simulation environment, Caedium, was available for the eagerly awaited iPad. Well sorry to disappoint, but we don't have a version of Caedium for the iPad - at least not yet - who knows what the future holds though.

Caedium on the iPad

Following hot on the heals of the recent Caedium release for the Mac, Caedium will also be available on the iPad when it is released on Saturday (April 3, 2010). In a worlds first, iPad users will be able to perform Computational Fluid Dynamics (CFD) simulations from the comfort of their sofa on the worlds most "magical and revolutionary product at an unbelievable price." The iPad version of Caedium makes full use of the multi-touch iPad interface, which enables you to control the actual fluid in the simulation in order to guide it to the answer you desire.

Affordable Desktop CFD

Bigger is always better when it comes to Computational Fluid Dynamics (CFD), right? Big computers, big simulations, big budgets - fine if you are a big aerospace company or a big Formula 1 team. Though, it's not so good if you are a small business or a hobbyist who wants to perform CFD simulations within tight budget constraints on a desktop or laptop computer. Don't despair - we are here to help. It is Symscape's mission to provide Computer-Aided Engineering (CAE) tools for all. We provide affordable software for performing meaningful CFD simulations on desktop computers.

Kennedy Space Center: Saturn V

After attending the 2010 AIAA ASM Conference in Orlando, I took the opportunity to bask in the Florida sun (if not heat - it was unseasonably cold, though still a whole lot warmer than New Hampshire in January) and visit the Kennedy Space Center. The highlight of the visit to Cape Canaveral was the Apollo/Saturn V Center, which houses a complete Saturn V rocket - follow along for a pictorial review of my trip with historical perspective thanks to Wikipedia.

Tailgate: Up or Down?

Debate rages (OK, maybe rages is a little strong) amongst pickup truck drivers as to whether it is more efficient to drive with the tailgate up or down. The urban legend is that running a truck with the tailgate down reduces the truck's drag and therefore improves its fuel economy.

3D Interaction Controls Revisited

Is it time for new interaction controls in 3D modeling applications such as Computer-Aided Engineering (CAE) analysis tools? Interacting with 3D models on a 2D screen has always been less than intuitive. However, a recent flurry of innovation in human-computer controls holds out much promise for the future of 3D model control.

Vertical-Axis Wind Turbine Drafting

A recent study into vertical-axis wind turbines (VAWTs) showed that their efficiency could be improved by arranging them into clusters to exploit drafting, i.e., placing VAWTs in the wake of other VAWTs.

New F1 Team Uses CFD Only

As the 2010 Formula 1 (F1) season approaches, excitement is mounting as a new batch of teams enters the ring. One such team - Virgin Racing (VR) - is hitting the headlines with their radical approach of only using Computational Fluid Dynamics (CFD) to test and develop the aerodynamics of their car.
