The authors of an Interface paper explain how their study applies large-scale computations to chart how the airflow evolves during a sniff, illustrating how the air we breathe moves inside our airways when we inhale. They explain how their results help our understanding of nasal physiology and could be helpful in treating medical conditions (Courtesy of Bates, Cetto, Doorly, Imperial College)
Initial temperatures in die and shot sleeve: Calculated initial temperature distribution via die cycle warm-up.
Meshing: Unstructured polyhedral mesh including thin layer at material interfaces for good prediction of thin section fill and precise calculation of high gradients.
Velocity Profile during a Sniff (Bates, Cetto, Doorly, Imperial College)
Large-scale computations to chart how the airflow evolves during a sniff, illustrating how the air we breathe moves inside our airways when we inhale. Shown here are velocity contours and vectors on a planar cut through the nasal passage (Courtesy of Bates, Cetto, Doorly, Imperial College).

The Access TechCenter provides an ideal environment for process engineering and component manufacturing via casting. Our main task: reach technological readiness and provide a production capability according to industrial standards. Access guarantees the transfer of its developments into industrial production and is ready to support implementation at the customer’s site. Access has been approved and certified to provide prototype parts for the new generation of aero engines and car engines.
Research into fundamentals of solidification and solid state phase transformations is essential. It enables us to accomplish a knowledge-based development of metallic materials for dedicated applications. We use state of the art experimental and analytical equipment, Thermo-Calc and our proprietary microstructure simulation software MICRESS® to comprehend the thermodynamics and kinetics of microstructure formation.
Access is an independent research centre associated with the Technical University of Aachen (RWTH) in Germany.
Harmonic Balance Solution View
STAR-CCM+ v9.06 includes the new Harmonic Balance (HB) Solution View for improved post-processing. The animation shows the pressure contours on the whole disc using the HB Solution View.
Spend time in the boardrooms or around the water coolers of Houston, and the subject will soon turn to the day’s oil price. Due to a combination of anemic global economic growth and, among other things, the supply side revolution of North American Shale, the oil price has plummeted by almost 30% in the past 3 months. As I write this blog WTI* is trading at a 5 year low, leaving the industry contemplating the considerable challenge of operating at $50 per barrel. While each company’s view on how to tackle this new paradigm will differ, for many it will be to continue the day job (deliver quality, innovative products and solutions), but at reduced time and cost, without compromising safety. It’s my belief that first principles approach, based engineering simulation tools such as those we (CD-adapco) deliver, will be a key enabler, as companies will increasingly rely on simulation based design exploration. The initial driver will be to reduce engineering cost and time, but they’ll also benefit from simulation as an innovation enabler.
