Pipe Fun With CFD

After replicating the classic pipes screensaver in Caedium for fun, the next obvious step was to run Computational Fluid Dynamics (CFD) simulations for each pipe network to ramp up the fun even higher.

Learn CFD Through Play

Rather than wait until your project schedule dictates it's time for Computational Fluid Dynamics (CFD) analysis, allocate time now to 'play' with CFD. By 'play' I mean construct simple geometry and keep your cases relatively small, so you can get familiar with the basic features of your particular CFD software in a timely manner.

Essential Apps To Compliment CFD

Enhance your Computational Fluid Dynamics (CFD) experience by considering some additional, freely available, complimentary apps. Combined with your CFD software these apps form a complete toolset for maximizing your productivity and, dare I say it, make it fun?

Weak and Strong Form CFD

If you are given production-ready detailed CAD geometry (nuts, bolts, and all) for Computational Fluid Dynamics (CFD) analysis you have to ask yourself, is this really an engineering endeavor or a marketing exercise? Given the effort to produce a complete, detailed CAD model, it is unlikely that any significant changes will be looked upon favorably. Instead you will likely find that CFD is to be used in its weakest form, i.e., Colorful Fluid Dynamics (CFD) for marketing.

CFD Helps Unconventional Concept Designs Succeed

When you find yourself tasked with the design of something unconventional, then Computational Fluid Dynamics (CFD) is here to help. For instance consider the aircraft industry. It used to be that the dominant type of aircraft required a pilot and therefore a cockpit with a good view of the world. Then Unmanned Aerial Vehicles (UAVs) went mainstream and everything changed.

How to Share Caedium CFD Results With ixCube 4-10

ixCube 4-10 is a comprehensive design tool for tensile structures, also known as membranes. By sharing your membranes with Caedium Professional you can perform Computational Fluid Dynamics (CFD) analysis to determine wind loads (e.g., pressure coefficient) and then export those results from Caedium and import them back into ixCube 4-10 for further stress and shape analysis. Watch the video for instructions on the process.

CFD For A Complete Dust Collector

Having performed Computational Fluid Dynamics (CFD) simulations for each component of Matthias Wandel's "Small Dust Collector," the time has come to assemble and test the entire system - virtually, of course. Recall that the main components of the dust collector are a cyclone, a filter assembly, and a blower.

Navier-Stokes Equations NOT Renamed

I'm sure you saw right through my April Fools' jolly jape and realized that the Navier-Stokes equations have not been renamed.

Navier-Stokes Equations Renamed

The International Equation Naming Organization (IENO) has renamed the Navier-Stokes equations to the Euler-Navier-Cauchy-Poisson-Saint-Venant-Stokes equations or ENComPaSS for short. You will no doubt recall that the ENComPaSS equations are the foundation on which much of modern day fluid dynamics is based, including Computational Fluid Dynamics (CFD), so this is indeed a momentous event.

Remote CFD is Easy

You know how it is - you are away from the office and you are desperate to check in on a series of Computational Fluid Dynamics (CFD) simulations you are running back at your base. Then once the simulations finish you'd like to take a moment to look at each one with all the benefits of hardware accelerated graphics on your laptop, while still enjoying your latte at Starbucks. Well you can do both today without any extra outlay using Caedium and free apps from Google - let me describe how.
