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-R: Analysing F-SAE Aerodynamic Flow Fields Using CFD
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.

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.
Meet the Expert Q&A: CFD in Tunnel Ventilation scenarios
Learn how simulation plays a vital role in the design phase for many infrastructure projects such as tunnels, with the ability to test various design configurations and verify performance virtually, without build-and-test methodology, providing cost savings and faster project delivery.
LEAP's Highlights from Ansys 2021 R1 Fluids release
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.
Using scripted “Record Blocks” to allow geometry parameterisation in SpaceClaim
How can CAE users make the most of the new scripting capabilities available in SpaceClaim 2020R2 to help efficiently automate the generation of new geometry designs? We look at how to create design templates that can automatically generate different designs, simply by modifying a few key parameters.
How to Improve Pump Efficiency through CFD Simulations
In order to improve pump efficiency, pump designers require fine-grain insights into complex fluid dynamics within a pump to help them identify areas that can be refined to reduce losses during pump operation. In this example, we look at the workflow to improve an existing pump’s design without requiring the original CAD drawings – instead using scanned data of an existing pump design.
Is your CFD simulation misbehaving? A troubleshooting checklist for challenging problems
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.
