In this section you will find all Rocky new features present in the 2025 R1 version.
Rocky Solver SDK New Features
Native calculations for strain rate tensor and velocity gradient vector was implemented and aims to facilitate the implementation of non-Newtonian fluid modules.
For more details see Rocky for Developers.
PrePost Scripting New Features
The support for creating custom curves and custom properties through Rocky scripting tool was added, enabling more automation capabilities to your simulations.
For more details see Rocky for Developers.
Point Clouds in Motion Frames
The Point Cloud feature enables you to import a text file containing field data that defines one or more points in space. Now with the 2025 R1 version it is possible to add this functionality along with Motion Frames.
For more details see Rocky User Manual.
See below the new features you can use to perform the Ansys Rocky coupling with Ansys Fluent® software:
Advanced option to use the DPM flow blocking approach for a single fluid phase 2-way unresolved coupling.
2-equation turbulence models support for 2-way semi-resolved coupling.
It was added the Fluent Cell volume and cumulative exchanged heat on geometries as new properties related to 2-way coupled problems.
Volumetric diffusion parameter to control the minimum number of the iterations of the algorithm.
Advanced option to increase the frequency of update of Fluent mesh coordinates when running 2-way coupled cases with mesh motion.
