Caedium v4 Sneak Peek: Tensile Membrane Structure Analysis

In the next version of Caedium you will be able to perform a CFD simulation of a tensile membrane structure and then export surface pressure coefficient (Cp) data for structural analysis in ixForten 4000. This exciting development will allow ixForten 4000 users to perform non-linear stress analysis to better determine membrane displacement with more precise wind pressure loads than previously available, leading to more cost efficient structures and supports.

Caedium v4 Sneak Peek: Centrifugal Compressor Passage CFD Simulation

We are still working on the next version of Caedium and thought it was time to share another update on Caedium v4 progress. This sneak peek highlights the new Caedium cyclic boundary condition along with other enhanced geometry tools that will enable CFD simulations of an idealized axisymmetric centrifugal compressor blade passage for instance.

Esperanto For Computational Fluid Dynamics

Big news from Europe - a new European directive has just been passed that requires all software applications released in the European Union to support the Esperanto language by June 2012. This is part of a larger European directive mandating that all European countries are to adopt Esperanto as the Europe-wide common language by 2014.

Caedium Helps Fastcination Win South-East German F1 in Schools Competition

Fastcination recently beat out 14 contenders to win the South-East German F1 in Schools competition. The German high school team used Computational Fluid Dynamics (CFD) simulations created in Caedium Professional to assess and improve the aerodynamics of their CO2 dragster.

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.
