Rocky DEM 4.5 simulation software is accelerating engineers’ use of particle modeling through improved computational speed, solver flexibility, and deeper integration with Ansys
Rocky 4.5 offers impressive speed across the board when compared to previous releases, with as much as 10x gains in calculation time.
Extended and deeper integration
Rocky 4.5 deepens integration with Ansys simulation software. Additional and new capabilities are available in four major areas: Multibody Dynamic (Ansys Motion), CFD-DEM (Ansys Fluent), Design Exploration (Ansys optiSLang), Simulation Data Management (Ansys Minerva).
Expanded Solver API
Over 30 new, ready-to-use modules have been added to the existing API library.
ESSS announces the newest release of its powerful Discrete Element Modeling software – Rocky DEM 4.5. This release delivers significant advances in solving particle dynamics engineering problems, enabling much faster solution of applications with large numbers of particles. Rocky DEM 4.5 also expands the innovation possibilities of particle-laden systems through expanded integration with Ansys simulation software, further supporting customers’ digital engineering strategies.
Release highlights include:
Increased ability to simulate free and rigid body motion through coupling with Ansys Motion multi-body dynamic software, helping engineers account for flexible components, kinematic forces, and link chains. Together with Ansys Motion, Rocky 4.5 performs analyses that consider the stress and deformation of flexible body components.
Expanded CFD-DEM capability now includes a broader range of particle-fluid applications, plus solutions for flows where particles are much larger than CFD mesh, all in a well-integrated workflow with Ansys Fluent.
Seamless integration with Ansys optiSLang supports model calibration and enables large-scale design exploration for design optimization and verification. In addition, Rocky users can now generate reduced order models (ROMs) for their process simulations to implement digital twins in Ansys Twin Builder and on a variety of software and hardware platforms.
Integration with Ansys Minerva for efficient simulation processes and data management.
Multi-CPU and multi-GPU improved performance and scalability for all applications. Performance tests for this new release showed impressive advancement across the board when compared to previous releases, with gains ranging from 50% to 1000%, depending on the application type.
Expanded solver API and GUI customization support, with an additional 30+ ready-to-use specialized physical modules. Rocky 4.5 expands the existing API library template available for customers to download. With additional exposure, users can do even more with Rocky, like working on their own breakage models and custom CFD coupling laws.
