• Modeling/Physics Enhancements - New modeling and physics enhancements this release includes the stiff chemistry solver and the eddy dissipation concept model compatibility with the Adjoint solver, useful for design improvements relevant to reacting flows. Electric arc modeling is now supported via Fluent-Maxwell coupling for applications such as welding arcs, electric switchgear arcs in gas, etc. For discrete phase modeling for multi- phase flows, coupling and radiation sources are now supported. Users can expect to see 10-20% speed-ups for conjugate heat transfer (CHT) calculations for applications with high solid-to-fluid mesh count ratios. Thermal abuse modeling enhancements have been made allowing users to evaluate abuse modeling parameters more quickly. Ansys CFX and Turbo Tools • Ansys BladeBuilder: As part of the Ansys BladeModeler product license, Ansys BladeBuilder has been launched as a new Discovery add-in that automates 3D CAD geometry creation for turbomachinery. This automates low- fidelity and high-fidelity CAD geometry creation for meshing complex blades in Ansys TurboGrid. • PyTurboGrid: Ansys TurboGrid can now be driven via Python scripts. This allows you to automate repetitive tasks, customize workflows and develop tailored solutions that align with your specific engineering requirements. • Hybrid Meshing: In Ansys TurboGrid, hybrid meshing now has beta support for high-fidelity blade features that intersect periodic boundaries, allowing you to mesh blades with end-wall contouring and casing grooves for example. • Updates to Blade Film Cooling in Ansys CFX: Updates to the Blade Film Cooling feature in Ansys CFX allows you to include platform leakage and trailing edge slots into your blade cooling models. Ansys Rocky • Perform DEM simulations leveraging new enhancements, including thermal coupling with Ansys Mechanical, analysis with particle transparency, and compatibility of liquid bridge with course graining. • Enhanced SPH capabilities set the foundations for faster simulation, gaining performance with the new incompressible SPH (iSPH) algorithm. SPH also has new viscosity models for non-Newtonian fluids simulation, 1- way coupling with Ansys Fluent, and ability to include effect of Heat Transfer Coefficient (HTC) without requiring a thermal solution. • User experience and automation improvements include PyRocky support, a new user interface with a style standardization and the dark theme, Rocky documentation made available under Ansys Help, and a Rocky space on AIS as a one-place for self-learning and community interaction. Ansys Chemkin • A new particle tracking feature has been added to the Chemkin Direct Injection Diesel Engine Simulator that can predict soot emissions. • Improved computational performance for flame models with multi-component transport facilitates increased simulation speeds by 1.5-2x for many use cases. • Additional efficiency and usability improvements have been made to Chemkin reactor models that allow you to end a simulation when ignition is detected, auto-populate the composition of air in all gas-phase reactant inputs, and add ignition times to CSV output files.
