October 2012: New Caedium Tensile Structure Tutorials
Since the release of Caedium v4, we've received a number of requests on how to perform CFD simulations for the air flow over tensile structures. If you are a tensile structures engineer then be sure to check out the two new Caedium tutorials we recently posted just for you. While you are here also catch up with a new electronics cooling CFD example and our recent blog posts.
You'll find a tensile structures (also known as membranes or double-sided walls) theme for our new tutorials.
Embed a membrane (face) from an Alias/Wavefront (.obj) file as a double-sided membrane in a flow volume. ixForten 4000 can export membranes as .obj files and this tutorial describes how to embed such a membrane in a flow volume ready for CFD analysis. Read more >>
Simulate an incompressible, steady-state, turbulent flow over a double-sided membrane. View velocity vectors, velocity magnitude color maps, monitor lift and drag forces, and export results for ixForten 4000. Read more >>
New RANS Flow Example
Have you ever wondered what Caedium can be used for?
Your choice of cooling fluid for an electronic device, can have a profound effect on its overall design and operation costs. So it's interesting to note that recent cooling strategies for computers include immersion of the entire computer in mineral oil as a cost-effective alternative to traditional air cooling. Which strategy do you pursue? Let CFD guide your decision - it is easy to switch the cooling fluid in a Caedium CFD simulation so you can make easy comparisons. Read more >>

While it seems that we are still a long way away from the cloaking devices seen in Star Trek, electromagnetic cloaking using metamaterials is becoming viable, at least in the laboratory. Not to be outdone, fluid flow and heat transfer have also recently joined the cloaking party. Read more >>
What if you could change the shape of a tensile structure according to the natural loads, such as wind forces, it experiences? In exploring this question researchers at the University of Stuttgart and the company Bosch Rexroth came up with a tensile canopy (membrane) - nothing new there. However, their novel design uses a feedback system driven by a sensor array connected to hydraulic rams that apply counter forces to natural loads. Read more >>
A recent study by Intel using Green Revolution Cooling's CarnotJet System described immersing computer servers in mineral oil for electronics cooling. Of course the question that springs immediately to mind is why would you want to submerge sensitive electronics in a liquid? Read more >>
