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.
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.
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
This blog series focuses on a common question: What y+ should I use in my simulations? This is Part 2 in the series – Resolving each region of the boundary layer.
This blog series focuses on a common question: What y+ should I use in my CFD simulations? This first post is designed to help you understand the physics of boundary layers in relation to CFD meshes and Y+ values.
