Fluid-structure interaction simulation of wave overtopping flow and vegetation for coastal hazard mitigation

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.

25th Anniversary of UNSW Redback Racing – A look back at Formula-SAE Aerodynamics Strategies

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.

How to approach hardware selection in 2024 for Ansys CFD solvers (all budgets considered – from laptops to clusters!)

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!)

Ansys 2023 Release Highlights – Fluids

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.

Simulating Aerothermal Shape Distortion of Hypersonic Vehicles

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.

A look into the lightning-fast future of GPU-powered CFD

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).

Exploring new ideas in Urban Design – a Q&A with Wendy Walls, Melbourne School of Design

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.

Highlights from SCONA 2023 – CFD of the Nose and Airway

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 by Prof. David Fletcher: Importance of following Best Practices for Scale Resolving Turbulence Modelling

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.

CFD Modelling of Biological methanation in bubble column reactors

Read how the advanced multiphase capabilities of Ansys Fluent (combining hydrodynamics with mass transfer and chemical reaction) are being used to model 3D bioreactors and used as inputs to validate simpler 1D models suitable for process design and optimisation using simpler, computationally faster models.
