May 2019: New Caedium Release and Tutorials

symscape — Tue, 21 May 2019 21:00:27 +0000

It is finally time to announce the new release of Caedium v6.0, headlined with the addition of Conjugate Heat Transfer (CHT) and Passive Species Transport. I know it has been a while, but some things take time and are the worth the wait - I hope this release is one of those things. In support of the new features are two new tutorials to get you started with CHT.

Enhanced CFD Simulations with Conjugate Heat Transfer and Passive Species Transport

The highlight of the latest Caedium (v6.0) release is an enhanced Computational Fluid Dynamics (CFD) heat transfer capability with multi-domain support for fluids and solids, known as Conjugate Heat Transfer (CHT). Also Caedium can now simulate the dispersal of secondary species (e.g., smoke or dye) in a primary fluid, known as passive species (or scalar) transport.

July 2017: Digital Paleontology with CFD

symscape — Tue, 18 Jul 2017 13:30:26 +0000

This month's newsletter has an unusual digital paleontology focus. Check out how Computational Fluid Dynamics (CFD) provides researchers with insights into how long-extinct creatures (everybody loves a dinosaur story or two, right?) might have interacted with their environments.

Long-Necked Dinosaurs Succumb To CFD

It turns out that Computational Fluid Dynamics (CFD) has a key role to play in determining the behavior of long extinct creatures. In a previous, post we described a CFD study of parvancorina, and now Pernille Troelsen at Liverpool John Moore University is using CFD for insights into how long-necked plesiosaurs might have swum and hunted.

CFD Provides Insight Into Mystery Fossils

Fossilized imprints of Parvancorina from over 500 million years ago have puzzled paleontologists for decades. What makes it difficult to infer their behavior is that Parvancorina have none of the familiar features we might expect of animals, e.g., limbs, mouth. In an attempt to shed some light on how Parvancorina might have interacted with their environment researchers have enlisted the help of Computational Fluid Dynamics (CFD).

April 2017: Fluidics and Stonehenge Vortex

symscape — Thu, 20 Apr 2017 19:32:36 +0000

It's April and therefore it's time to confess that there isn't a solstice day vortex generated at Stonehenge, unless you are in the April Fools' Day distortion field. However, there are fluidic components that mimic digital logic gates.

Fluidic logic (fluidics) uses specially designed fluid paths to perform logic operations, such as AND, OR, and NOT gates. In electronics logical operations underpin all the digital devices that depend on CPUs for their brains. Using Computational Fluid Dynamics (CFD) we can quickly explore potential fluidic components.

March 2017: CFD and Aerodynamics

symscape — Tue, 21 Mar 2017 20:21:33 +0000

The two themes for this month's newsletter are Computational Fluid Dynamics (CFD) and aerodynamics. First check out our revamped CFD description now with a what, why, and how treatment. Next see how aerodynamics can help you go dangerously fast downhill. Then finally, discover the aero effects of fenders (mud guards) on your bicycle wheels.
