Coming soon to a computer near you - the next version of Caedium will be able to exchange geometry and flow data with ixForten 4000 for an enhanced tensile membrane design process. See our latest sneak peek for more details on this highly anticipated membrane exchange capability. As always, you can catch up with our latest blog posts too.

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.

London 2012 Olympics: Fluid Technology for Swimming

With the London 2012 Olympics just around the corner, I thought it would be interesting to review the application of fluid technology to various Olympic sports, starting with swimming. Read more >>

Wind Turbine Crossed with a Blimp

Another helium-filled post - this time it's a helium-filled blimp that houses a horizontal-axis wind turbine [source: gizmag]. Altaeros Energies recently released a video of their prototype Airborne Wind Turbine in action. Read more >>

Tetrahedra Take Flight

Who knew that tetrahedra could fly? I know, pretty much anything can fly when you fill it with helium, but the movement of helium-filled tetrahedra called SmartInversion by Festo gives rise to an interesting and unusual propulsion method [source: gizmag]. Using inverse kinetics, Festo have developed what they call an "airborne geometrical band with inversion drive". The movement is difficult to describe but mesmerizing to watch. Read more >>

Fishy Fluid Dynamics

Fishermen at Lake Como, Italy, have shown remarkable knowledge of the complex water currents in the lake. Researchers found [source: Science Mag] that the fishermen's knowledge correlated well with independent observations and Computational Fluid Dynamics (CFD) simulations. The primary means the fishermen use to monitor water currents is by the deformations the currents cause in their large nets once deployed in the lake. Read more >>
