David Fletcher from LEAP discusses the importance of the 3rd Turbulence Best Practices guide recently released by Florian Menter and his team at Ansys.
This latest BPG documents the key best practices in RANS turbulence modelling, with comprehensive coverage of all widely-used 1-equation, 2-equation and Reynolds stress models.
Summary of a recent webinar presented by Prof. David Fletcher on how to take advantage of the powerful python-based expression language now available in Ansys Fluent. Examples shown included the use of expressions starting from scratch, plus examples showing how to convert your existing CFX CEL into Fluent expressions.
Guest blog by ECU-Racing on how the team uses CFD simulation to drive aerodynamic design improvements, explaining how CFD simulation results provide help identify problematic aspects such as flow separation, undesirable flow structures, and poor use of flow energy which can then lead to new ideas which can be tested in CFD to improve the overall flow around the car.
Learn how recent developments in Ansys provide a new “optical CFD” workflow to help more accurately simulate the complex interactions between the flowfield and electromagnetic fields in the Electro-Optics / Infra-Red (EO/IR) range. This helps engineers to improve their simulations of flow field phenomena around fast-moving vehicles and improve the performance of EOIR sensor signals for tracking hypersonic vehicles.
Prof. David Fletcher guides us through the key new features of interest in Ansys 2021 R2 for CFD, including some important new usability enhancements. This blog contains a series of short summaries with content tailored to particular physics / applications / topics of interest.
Read about Monash High-Powered Rocketry's amazing achievement to win second place in its category at the 2021 Virtual Spaceport America Cup - including an acknowledgement of their quality simulation work, with first place in the Charles Hoult Award for Modelling and Simulation.
Ansys 2021 R1 brings a multitude of new advances and usability enhancements. - here we provide a series of short highlight summaries with content tailored to particular physics / applications / topics of interest.
Guest Blog by USYD Rocketry Team (URT) who use simulation in their development of high-power sounding rockets to compete in the Australian Universities Rocketry Competition (AURC) and Spaceport America Cup. URT was the first Australian team to compete and took first place in the 10,000 ft COTS category with their Silvereye rocket.
For the times when your CFD simulation is diverging or not behaving as expected, we offer a helpful checklist to systematically troubleshoot what is going wrong and successfully tackle the most challenging CFD problems.
This blog series focuses on a common question: What y+ should I use in my simulations? This is the final part (Part 3) in the series – Understanding impact of Y+ and number of prism layers on flow resolution in our CFD simulations
