A new Caedium release is ready and waiting with a couple of new features and bug fixes. Are you confused by how your solid model relates to a Computational Fluid Dynamics (CFD) flow volume, or were you wondering how the fluid dynamics of a sphere affects ball sports, then this is the newsletter for you.

'Tis the season to be whimsy, tra la la la la, la la la la' ... and so off to a Computational Fluid Dynamics (CFD) whimsy holiday season we go with a Caedium simulation of an elephant collapsing into a puddle. Also joining us are a couple of whimsy-themed blog posts. Thanks for your support during 2013. We are looking forward to serving your CFD needs in 2014 and beyond.

When Computational Fluid Dynamics (CFD) speaks it usually has interesting things to say. Our feature this month is a CFD study of car aerodynamics. Also you can browse a selection of general interest blog posts - one even relates to dinosaurs! Finally, listen to a podcast interview, "Rich Smith on CFD that won't break the bank", I did with Jeff Waters (Life Upfront blog) on the founding of Symscape and the development of Caedium, which targets small engineering consultancies.

This month I have a special feature newsletter for you that gathers together all the recent wind tunnel Computational Fluid Dynamics (CFD) blog posts, including a new two part series which compares a virtual wind tunnel with free air for an open wheel racecar. The Caedium Professional simulations show that even though the Reynolds number is different between the wind tunnel and a full size simulation, the results can still be useful in guiding the aerodynamic design of a racecar.
