enhancements have also been made to improve the post-processing experience. In Fluent Desktop, case setup operations are 3-500X faster for cases with many zones, greatly reducing pre-processing times for large assemblies such as battery packs. Finally, transient post-processing can now be performed directly within the Fluent solver for an improved workflow. • Fluent CPU Solver Physics Updates: New physics enhancements have been made in 2025 R1 to improve industry-specific application workflows. For Li-battery simulations, solver robustness improvements have been made to significantly improve convergence, enabling orders of magnitude speed-ups. For designs with rotating blades, such as helicopters and drones, automation enhancements have been made to the virtual blade model (VBM) to create floating disks automatically before solving. New ice shapes and models are available within the Fluent Icing Workspace for in-flight icing studies. • Meshing Enhancements: Task-based performance improvements have been made to the fault tolerant meshing (FTM) and watertight meshing (WTM) workflows to improve meshing speeds, for example a case with 200k parts in now 30X faster. Cell zone copying and zone merging is now significantly faster, reducing setup times for applications such as battery cell modeling. Additionally, modular wrapping is now available for very large models to simplify sub-assemblies before meshing the full model—enabling faster meshing speeds easier manipulation/inspection. Ansys CFX • A new parallel approach for Harmonic Analysis (HA) partitions the simulation by time planes, providing a speed up approximately equal to the number of time planes. For example, an HA simulation with 9-time planes is now approximately 9x faster. • New adaptive and dynamic steam tables optimize accuracy and computational time for steam turbine analysis, adjusting dynamically the temperature and pressure table range as the solution evolves. • CFX's virtual injection hole model can now better replicate the fully resolved model for blade film cooling applications by imposing a choke condition to restrict the local Mach number.
