What's New
In 2024 R2, Ansys Fluent continues to deliver critical enhancements to improve solver performance, end-user productivity, and added capabilities to industry-specific workflows.
Expanded Use Cases and Hardware Options for the Fluent GPU Solver
Support is now available to run the Fluent GPU solver on AMD GPU cards, enabling broader hardware options for our users. Added physics includes compressible flows, DO radiation, anisotropic conductivity, and more.
New Functionality for the Fluent Web Interface
The Fluent Web interface allows you to connect or launch your Fluent simulations on a web browser and start/stop/pause your simulations in real time. Updates in 2024 R2 include limited model set-up support, a template to connect to HPC, a multi-select context menu, and more.
Advancements for Aerospace Use Cases
Updates to the Fluent Aero workspace (dedicated to external aerodynamics studies of aerospace applications) include compatibility with the virtual blade model (VBM) with the DBNS solver. Parametric post-processing is also now available to post-process numerous design points simultaneously. Automated PUMA mesh adaption is also now available.
Fluent Updates for Aerospace Applications
Aerospace application updates include accuracy improvements to the two-temperature equation model for high-speed flight regimes that now match better with measured data. The Virtual Blade Model (VBM), widely used for rotorcraft and urban air mobility applications, now includes additional outputs, including Xp-force and Yp-force.
PyFluent Improvements
PyFluent updates include an improved workflow interface for a cleaner and more efficient programming style, new API availability to access and modify volumetric solution data, and usability improvements of field-data APIs with a purpose-designed interface for more straightforward interpretation.
AI/ML for Turbulence Modeling
Turbulence model tuning with AI/ML is now available. The adjoint solver and AI/ML calibrate GEKO coefficients against a high-fidelity LES solution, yielding LES-level accuracy at the cost of RANS.

Best Practice: Generalized k-⍵ Two-Equation Turbulence Model in Ansys CFD (GEKO)D
Ansys developed a new turbulence model family called Generalize k-w (GEKO) model with the goal of turbulence model consolidation. GEKO is a two-equation model, based on the k-w model formulation, but with the flexibility to tune the model over a wide range of flow scenarios.
