Overview of Ansys 2023 R1 Fluids

In Ansys 2023 R1 Fluids product line is pushing the envelope of performance, fidelity, sustainability, and productivity for computational fluids dynamics (CFD) simulations. The full release of the multi-GPU solver in Fluent is unleashing the power of multiple GPUs for a broad spectrum of applications and the accurate hydrogen modelling throughout its value chain is helping to address comprehensively the sustainability challenges in transportation and energy industries. Workflow and automation improvements across the entire product line are resulting in faster, more efficient simulations, thus reducing the design cycles. To see which feature can benefit you, check out the detailed list below.

Release highlights

Ansys Fluent

  • Run broad spectrum of complex industrial applications natively on GPUs substantially reducing solve time and total power consumption, with results showing 6 high-end GPUs provide the same performance as more than 2,000 CPUs.
    • This full release added support for species transport, non-stiff reacting flows and enhanced numeric for LES simulations.
    • Support for sliding mesh and compressible flows simulations has also been added in addition to the full released features (beta).
  • The new Proton Exchange Membrane (PEM) and Alkaline electrolysis models for green hydrogen production and the extended Polymer Electrolyte Membrane (PEMFC) and Solid Oxide (SOFC) models for hydrogen consumption in Fuel Cells enable accurate hydrogen simulations throughout its entire value chain.
  • A new embedded workflow for parametric design optimization and morphing enables to run parametric studies and design optimization, including morphing, directly within the Fluent interface thus speeding up design cycles.
  • A new embedded PyConsole brings PyFluent directly in the Fluent interface with support for centralized Python journaling, full scheme/TUI to python journal translation and usability features like auto-complete and quick search of Fluent commands (beta).
  • A Virtual Blade Model (VBM) includes the effects of 3D rotors as momentum source terms in the governing equations, increasing automation and productivity for aerospace and energy applications (beta).
  • Access High-Speed Numerics (HSN) within the Fluent Aero Workspace with seamless setup and improved robustness and convergence for all flight regimes.
  • Perform advanced electronics cooling analyses that can include condensation, evaporation and more, with a new direct ECAD workflow for printed circuit board (PCB) that enables the import of an ECAD directly from the Fluent interface without additional software required.
  • Compute Optical Path Length / Optical Path Difference (OPL/OPD) due to aero-optical aberrations directly in Ansys Fluent and to export them to OpticalStudio for more sophisticated optical analyses (beta).
  • Generate photo-realistic renderings of your simulations with live preview, custom environments, material editor, light presets, etc. with the new OSPRay raytracing engine available in Fluent (beta).

Ansys CFX and Turbo Tools

  • A new plugin streamlines the workflow for using the CFX Solver in optiSLang, enabling to run design points concurrently and to leverage optiSLang’s parametric licensing.
  • You can now add blade blends, create partial tip geometry at the hub/shroud and adjust the blade stagger angle directly in TurboGrid. Use profile/curves as the input geometry, then TurboGrid will automatically create the high-fidelity CAD with the additional blade features and produce a high-quality mesh.

Ansys Rocky

  • Fully integrated SPH (Smoothed-Particle Hydrodynamics) solver with upgraded unified user interface (setup and post processing) to create a single SPH-DEM workflow environment. The new release provides an efficient simulation workflow for modeling particle-laden free surface flows and adds heat transfer between the particles, fluids, and walls.
  • Extending simulation domain flexibility to include inlets and outlets for both particles (DEM) and fluids (SPH elements) provides a range of flexibility to set up particle and fluid injections, accelerate geometry and problem set up and easy accounting of mass flows within the domain and the boundaries.
  • Expanded coupling with Ansys Fluent highlighted by usability improvement through Rocky-Fluent two-way coupling in Ansys Workbench. The new release also provides more accurate heat transfer calculations for particle-laden flows by including particle-wall heat transfer models.

Ansys Chemkin-Pro

  • Accurately simulate Zel’dovich/von Neumann/Döring (ZND) explosive detonations with a new end-to-end workflow that includes enhancements in the treatment of the incident shock speed in the Chemkin-Pro shock model.
  • A new Plasma Multiphase Perfectly Stirred Reactor (PSR) enables accurate prediction of plasma-water processes like the carbon-free ammonia production and the removal of toxic substances (beta).

Ansys Forte

  • A new Arc Channel Tracking (ACT) spark model improves accuracy and enables to capture short-circuit and restrike events when simulating ignition and flame propagation in IC Engines.
  • A new moving monitor probe with prescribed movement allows tracking properties of a fluid pocket as it moves from the suction to discharge ends in pumps and compressors simulations.
  • A new runtime framework providing time-averaged statistics for any spatially resolved flow variable improves productivity for Large Eddy Simulations (LES) and quasi-steady conditions analyses.

Ansys FENSAP-ICE and Fluent Icing

  • Accurately capture local blockage and flow redirection to uncontaminated parts of wire mesh screens (e.g., Engine FODs) with a new Screen Icing Model accounting for total pressure losses in FENSAP-ICE.
  • Perform what If studies, sensitivity analysis, build custom design of experiments and more with the new Multiphysics Parametric Exploration in Fluent Icing.
  • Perform steady state simulations of electro-thermal and hot air anti-icing systems with a simplified workflow directly in Fluent-Icing (beta).

Ansys EnSight in Ansys 2023 R1 Fluids

  • Improvements in rendering, including Lighting Presets, Light Attenuation and SPH OSPRay rendering increase the end-user productivity and usability.
  • The OSPRay engine can now get lighting instructions to ray trace the geometry from HDRi images for a more realistic rendering of simulation results (beta).

Ansys System Coupling

  • Introducing PySystemCoupling package for easy access to System Coupling, allowing flexible integration between other PyAnsys products as well as wider Python developer ecosystem.
  • Add support for mapping of complex mode shapes from Mechanical modal analysis to CFD blade flutter analysis to perform aerodynamic damping analysis.
  • User interface improvements, including ability to view participant transcripts in the System Coupling graphical user interface.
