Ansys CFD

How to approach hardware selection in 2025 for Ansys CFD solvers (all budgets considered – from laptops to clusters!)

Working at the bleeding-edge of engineering simulations, LEAP’s engineers are frequently asked for advice from our clients across many different industries, who are looking to successfully navigate the balance between cost and optimal solver performance when purchasing new hardware. The following advice is primarily based on LEAP’s accumulated recent experience with a particular focus on CFD workloads (Ansys Fluent), as FVM codes are capable of scaling incredibly well if the system is well designed.

Australian team Lunar crowned 2025 STEM Racing World Champions in Singapore

Team Lunar has been competing in STEM Racing since 2022, and has become one of the most dominant Australian teams in the program. The team placed 3rd at the World Finals in Saudi Arabia in 2024, and won back-to-back Australian National Finals. From Brighton Grammar School in Melbourne, the team comprising of 5 year 11 students: Leo Jansen, Max Zylberman, Oliver Chernikeeff, Liam Jones and Max Zhou has become the eighth team from Australia to be crowned STEM Racing (formerly F1 in Schools) World Champions, supported with LEAP’s industry-standard simulation and 3D rendering software.

From Shark Skin to Heat Exchangers: Biomimicry + Simulation as an Engineering Framework

Dr. Aakash Shaun Hurry’s PhD research set out to answer a simple but powerful question: can inspiration from nature help us design more efficient heat exchangers? In this guest blog article, Dr Hurry describes how he used a combination of CFD simulation, additive manufacturing, and laboratory testing to explore how the microscopic scales of shark denticles could be applied to heat exchanger fins to improve heat transfer and overall performance.

Expert Tips on tuning the GEKO turbulence model

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”. Read on to learn more.

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.

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).
