This article answers the question, “What is special about the GEKO model compared with all other two equation RANS models?” The result of the decades of experience that Dr. Florian Menter has acquired through his vast experience of turbulence modelling at NASA and Ansys, the GEKO model is very much the culmination of a life’s work on improving turbulence models to make them what he calls “industrial strength”.

Climate change is increasing the exposure of communities to coastal hazards and traditional solutions, such as seawalls or revetments, can have a high financial, social and environmental cost. As a result, nature-based solutions are encouraged in coastal policy. This guest article by University of Auckland’s Joshua Bagg, Mark Battley, Colin Whittaker and Tom Shand describes their unique research aimed to investigate the interaction between salt marsh grass and wave overtopping flow using Ansys Fluent and Ansys Rocky to inform the design of nature-based solutions.
Founded in 2000, The University of New South Wales (UNSW) Formula SAE Team, UNSW Redback Racing has continued year on year to design, build and race in the Formula SAE Australasia competition. With each car, the team strives for improvement and innovation, building on previous designs and advancing their knowledge into the future. An important part of this process is the use of Ansys Simulation for their Aerodynamics package and in this article, the team outlines their aerodynamics simulation strategy, explaining how they got to their current design, and their plans for the future.
Note: This was written in December 2023, but this is an ever-changing space, so please contact your local LEAP support engineers if you would like… Read More »How to approach hardware selection in 2024 for Ansys CFD solvers (all budgets considered – from laptops to clusters!)
Recording from LEAP’s recent series of Ansys 2023 R1 & R2 update seminars covering the latest updates in Ansys Fluids. Thes videos are from our Melbourne event, presented by Dr. Lewis Clark, LEAP’s Fluids Technical Manager.
How can designers of hypersonic aircraft overcome the ‘heat barrier’ using simulation to better understand aerothermal shape distortion (aka aerothermoelasticity, or fluid-structural-thermal interaction – FTSI)? This guest blog by ADFA explains how multiphysics simulation helps designers of hypersonic vehicles account for aerothermal shape distortion (which can compromise a hypersonic vehicle’s aerodynamic performance) through to the risk of catastrophic material failures, using tools that can simulate both the aerodynamics as well as the thermal and structural response.
Here we benchmark Fluent’s new fully-native GPU (Graphics Processing Unit) solver, available since the 2023R1 release, which has delivered impressive numbers on our tests that include both high-end (A100 GPU – over five times faster than a baseline using 80 CPU cores) and standard 8GB GPUs that are probably similar to one you’re already using (still delivering a 3x3x speedup over an 8 core Intel Xeon W-11955M CPU).
Q&A with Wendy Walls whose research and teaching aims to deliver innovative design methodologies for urban open spaces, designed in response to a changing climate. Learn how Wendy’s use of Ansys Discovery has provided an engaging way to teach landscape design students the critical concepts involving airflow and heat transfer in urban design.
Our curated highlights from a recent SCONA event (SCONA is the Society for Computational fluid dynamics Of the Nose and Airway) that illustrate the power of using CFD for applications relevant to our understanding of the nose and airway. SCONA 2023 was held recently in Brisbane, Australia.
Guest Blog explaining the significance of the new Stress-Blended Eddy Simulation (SBES) turbulence approach which makes use of the best available models for both near-wall and far field accuracy, within one single scale-resolving CFD simulation, including a recording of highlights from our recent webinar.
