©2026 ANSYS, Inc. 2 Some key areas of the Ansys Rocky 2026 R1 enhancements Ansys Rocky fosters particle simulation beyond traditional DEM DEM Simulation Engineering Copilot: AI-enabled assistant. Flat Plate HTC Correlation module. Mixing Index Calculator: A new script to automate the calculation of the mixing index for multiple materials. New Modules available: Intermolecular Forces and 1-way Free Surface, to implement different types of fluid and intermolecular forces (without the need of CFD Coupling). MPI-based parallelization (Beta). Optimization of the volumetric generation of DEM/SPH elements. Extend SPH Flowmeters: Measures the average of velocity (or temperature) of the flow over a given surface. Enhanced usability when creating particle inlets through PrePost Scripting (automation). Multiphysics Coupling Performance & Usability 1-Way Fluent GPU-Rocky support. Rocky Unresolved + Fluent VOF support: New support using the VOF multiphase approach in the 2-Way CFD coupling. Buoyancy force using fluid expansion coefficient: Natural convection on SPH models for predicting wall heat transfer rate at complex boundary (Beta). A new enhanced version of the integration between Rocky and Ansys optiSLang. 1-Way constant torque law for viscous dissipation of rotations.
