What's New in Rocky 2023 R1.0 (23.1.0) - Date: January 2023
In 2023 R1, Ansys Rocky provides SPH-DEM workflow and usability enhancements along with improvements in the two-way coupling with Ansys Fluent.
SPH Improved Workflow and Usability
Fully integrated Smoothed-Particle Hydrodynamics (SPH) solver with a unified user interface creates a single SPH-DEM workflow environment
Extended Domain Flexibility
Extended simulation domain flexibility includes inlets and outlets for both particles and fluids, enables the set up of particle and fluid injections, accelerates geometry and problem set up, and accessible accounting of mass flows within the domain and boundaries
Enhanced Coupling with Ansys Fluent
Two-ways Rocky-Fluent coupling directly in Ansys Workbench with more accurate particle-wall heat transfer calculations for particle-laden flows



Rocky DEMis a powerful, 3D discrete element modeling (DEM) program that quickly and accurately simulates particle behavior within a conveyor chute, mill, or other materials handling system. Rocky analyzes media flow patterns and energy absorption rates, particle breakage, and energy spectra analysis. The software optimizes life expectancy of conveyor belts and components, minimizes material spillage in a design, and reduces the need for dust control and suppression, among numerous other applications. This software is a revolutionary way to handle a problem through computer simulation. With ROCKY for ANSYS particle simulation can be extended with important structural and flow-mechanical information. These are achieved by a complete integration in ANSYS Workbench. The compact and user-friendly user interface of ROCKY for ANSYS ensures uncomplicated installation and operation. CAD geometries can also be imported easily and quickly. The 2023 R1 version of Rocky includes significant advancements with a fully integrated SPH solver and expanded coupling with Ansys Fluent.
