What's New

Continuing to push the boundaries of performance, productivity, and capability for CFD simulations

The 2023 R2 release delivers significant enhancements that improve performance through the multi-GPU solver, increase end-user productivity with automation and insights, and extend the capabilities to address ever-growing complexity in customer CFD applications.

  • Unleash the power of multiple GPUs with new support for rotating components with sliding mesh, compressible flows, and EDM combustion simulations
  • Quickly view and edit model and solver settings, monitors, and post-processing settings without having to load the mesh – opening a 6 billion cell case in as little as 80 seconds
  • Access additional solver settings within PyFluent for DPM, radiation, species transport, VBM, mesh interfaces, and more, broadening the range of applications for automation
  • Significant enhancements for aerospace applications include a Virtual Blade Model, a built-in Aero-Optical workflow, and a new ability to account for weak ionization at hypersonic speeds to predict communications blackout in Ansys Fluent
  • Automate meshing for hydro-turbines, including the ability to mesh Kaplan and Francis turbines with square trailing edges with Ansys TurboGrid
  • A new Volume of Fluids (VOF) capability is now available in Ansys Forte, providing an enhancement allowing the simulation of oil injection in screw compressors and pumps
  • Ansys Rocky includes new post-processing capabilities, featuring streamlines, flow tracers, and innovative boundary interaction statistics such as wet time and heat transfer
