July 2014: Reduce Your CFD Simulation Size by 50% or More

In this summer vacation edition newsletter read how you can slice and dice your Computational Fluid Dynamics (CFD) models to exploit symmetry and thereby reduce your simulation sizes by 50% or more. Do you need inspiration for what to do with your new found CFD smarts over the summer? Then take a look at the articles below on the air flow around airships and through World Cup stadiums. It's all here.

Speed Up CFD with Symmetry and Cyclic Conditions

Symmetry (or planar symmetry) and cyclic (or rotational symmetry) boundary conditions for Computational Fluid Dynamics (CFD) can often save you 50% or more in simulation turnaround time. Alternatively you can use the freed up memory to run more accurate simulations with more mesh cells clustered in areas of interest. Clearly these simulations are worth considering if your model satisfies the symmetry or cyclic criteria.

World Cup Stadium Aerodynamics with CFD

The 2014 FIFA World Cup is well underway and the final match to crown the world champions will be played in the MaracanĂ£ Stadium. The stadium was originally built to host the 1950 World Cup final, but with the stadium being the focal point for the current 2014 World Cup and the upcoming 2016 Olympics it was deemed that it needed a revamp. The most striking difference between the old and newly renovated stadium is the roof that now protects 95% of the seating from rain and provides better shade. The original roof only offered minimal rain protection and shade to a few rows of seats. However, it seems little air-time has been devoted to analyzing the wind characteristics of the playing area inside the stadium due to the different roof extents, especially when you consider how much attention the aerodynamics of the match ball have garnered. Rest easy though, Computational Fluid Dynamics (CFD) is here to help.

June 2014: World Cup Edition

This month's articles take you from the meshing world cup to the actual World Cup. The 23rd International Meshing Roundtable is running a mesh competition (the nearest thing the mesh world has to a world cup) based on London's Tower bridge, so see if you think Caedium Professional has what it takes to be a contender. Then there's the actual World Cup and, if aerodynamics is your thing, all that matters is the ball.

Tower Bridge Meets CFD

Complete, watertight, complex geometry is a rare but welcome find in Computational Fluid Dynamics (CFD). However, thanks to the steering committee of the upcoming 23rd International Meshing Roundtable, such a geometry, in various formats, is freely available for their meshing contest. The star of the contest is London's Tower Bridge, I presume in honor of the conference's host city. So to the bat cave to see what Caedium Professional can do with this model.

May 2014: Sneak Peek at Passive Species

It's time you heard about progress on the next Caedium release, right? This can only mean one thing - sneak peek season is upon us with a preview of the new passive species transport capability coming to a Caedium near you soon. Let's not forget that Caedium also has a wide range of existing capabilities, so why not take a moment to see how to make a splash using Computational Fluid Dynamics (CFD)?

How to Make a Splash in CFD

It is a common occurrence: a rain drop falls into a puddle; a leaky faucet drips into a sink of water. This seemingly simple event has some complex physics in play that advanced multi-phase, free-surface (volume of fluid - VOF) Computational Fluid Dynamics (CFD) can simulate. Not only can CFD simulate water impact in a pool, it can also produce a beautiful 3D visualization of the process as an animation. Follow along to see how you can use Caedium Professional to simulate a water droplet falling into a pool of water.

Caedium CFD Sneak Peek: Passive Species Transport

The next release of the Caedium CFD software system will be able to simulate the convection and diffusion of a passive species, also known as a passive scalar. A passive species can represent and track additions such as smoke in airflow and dye in water. It can also provide insights on the dispersion of pollutants carried by a fluid.

April 2014: 3D Visualization, Turbulence Modeling, and Automation

3D visualization explained, diagnosing turbulence model issues, and Computational Fluid Dynamics (CFD) task automation using Caedium's Python scripting - a technical reading list for you this month. Too much? Then lighten the load with some April Fools' Day posts on the aerodynamics of stationary bicycles.

Automated Creation and Export of CFD Results

Previously I showed how to automate a sequence of Caedium Computational Fluid Dynamics (CFD) simulations of an alpha sweep for an airliner. Next up I will show you how to automate the export of results from Caedium in a specific format. This example focuses on the files required for ixCube 4-10 (the successor to ixForten 4000) to perform a structural analysis using the pressure coefficient (Cp) from an airflow simulation over a tensile structure or membrane.
