What’s New for Rocky in Ansys 2024 R1

In 2024 R1, Ansys Rocky continues to address customers' needs by delivering features that enable users to perform accurate discrete element method (DEM) simulations. This release keeps the focus on multiphysics, provides new smooth particle hydrodynamics (SPH) capabilities, and optimizes user experience, which creates limitless possibilities in particle dynamics simulation.

Take a look at some of the new functionalities.

Two-way Thermal Coupling Between Rocky and Mechanical

This release brings a significant leap in equipment thermal analysis with the implementation of two-way thermal coupling with Ansys Mechanical.

Users can now run thermal simulations in which particles and equipment affect each other in thermal solutions simultaneously, amplifying insights and boosting the depth of thermal analysis.

Coarse-grained Modeling Extension

The coarse-grained modeling capability was extended to cover the liquid bridge adhesion model and SPH-DEM coupling, unlocking the ability to speed up more complex particle simulations.

Improved Visual Analysis

Particle transparency functionality is very useful for visual analysis, mainly for simulations with a shell particle shape (like plastic bags, leaves, potato chips, pieces of fabric, etc.).

Elevating SPH Capabilities with Rocky

Discover fresh perspectives in fluid simulation by leveraging new state-of-the-art SPH capabilities for enhanced insights.

Incompressible SPH (iSPH):Through this beta module, you can use a new algorithm for computing pressure that speeds up simulation by four times compared to the default SPH formulation.

Heat transfer coefficient on walls: You can now calculate the heat transfer coefficient (HTC) on walls to conduct convective thermal analyses of equipment.

SPH point cloud air drag module: This beta feature accounts for the interaction with a static velocity vector field representing airflow in a one-way coupling scenario with Ansys Fluent when solving the liquid phase using Rocky’s SPH solver.

Non-Newtonian Models: The dynamics of fluids, like ketchup, require non-Newtonian viscosity representation to be properly modeled and simulated. Rocky has three new viscosity models, which allow users to capture the behavior of non-Newtonian fluids.
