In this section you will find new Rocky Modules and main enhancements present in the 2025 R1 version.
Rocky New External Modules 2025 R1
EMAG (External Module)
The Electromagnetic Coupling module enables you to add electromagnetic physics to the simulation, such as:
Electrostatic forces for particle-particle and particle-boundary interaction;
Charging and discharging effects on particles due contact with boundary surfaces;
Field forces on charged or dipole particles immersed on electric/magnetic fields.
This module replaces the: Electrostatic Force, Magnetic Force and Magnetic Force Ferrous and Tribocharing External Modules.
Thornton-Ning Normal Force Module (External Module)
This module enables you to use the Thornton-Ning Normal Force for the Normal Forces used in the project. In Rocky software, the Normal Force is used to calculate the normal components of the contact forces, and will therefore affect particle-particle and particle-boundary interactions.
To download the Rocky External Modules, in the Download Center page on Ansys Customer Portal scroll down to Add-ons Packages, and in Ansys Rocky click on SDK and Modules to download all modules available
For more details see Rocky Module Manual.
Rocky New Internal Modules 2025 R1
Multibody Dynamic (Internal Module)
This module replaces the FMU, Ansys Motion Coupling and Adams Coupling External Modules, in this way with just one module you can import FMU into Rocky software.
Note: To do the export from Ansys Motion™ Software and Adams you can use the Ansys Motion Coupling and Adams Integration External Modules that continue available in the Additional Package.
Note: The FMU External Module is not available in the 2025 R1, since the Multibody Dynamic Internal Module fully replaces this module functionalities for FMU import and export.
Rocky Internal Modules are embedeed in Rocky Software and can be activated in the Modules parameter on Data Panel.
For more details see Rocky User Manual.
