The ESSS product team (part of CADFEM) has presented an updated Rocky DEM 3.10. The 3.10 release of Rocky DEM software brings new features including thermal modeling, Eulerian Statistics, and support for ANSYS 17.0.

Rocky DEM Software 3.10 - Release notes:

Rocky DEM release 3.10 brings new features that help users perform more accurate and complex simulations. Included in this latest release are the Eulerian Statistics user process, thermal modeling capabilities, and support for ANSYS 17. The user manual has also has been converted to an easier-to-navigate and search topic-based platform, and includes new documentation on both the Eulerian Statistics and the thermal modeling features.

Thermal Modeling
One of the highlights of Rocky DEM 3.10 release is the ability to simulate particle-to-particle, particle-to-boundary, and particle-to-fluid (when coupled with a CFD solver) heat transfer. This new thermal model allows the simulation of equipments that deal with particle heating (or cooling) and provides a detailed view of the particle temperature behaviors in the system. This feature, for example, is a useful way to study heat transfer in granular materials in rotary calciners, helping engineers to design and optimize their materials handling equipment.

Eulerian Statistics
Another highlight of this release is the Eulerian Statistics user process. It is allows users to partition the space represented by a Cube or Cylinder user process into discrete regular blocks for further particle data analysis. The user can control the number of blocks by specifying how many divisions are required in each of three directions. This feature works together with another new user process called Cell Inspector that allows users to analyze individual cells that make up entities, such as geometry triangles or Eulerian Statistics blocks. The Cell Inspector might be especially useful for Eulerian Statistics as it more easily enables the analysis of individual blocks.
ANSYS 17.0 Support
This new version of Rocky DEM now supports ANSYS 17.0 on the Rocky DEM - ANSYS Workbench coupling for one-way structural analysis and on Rocky DEM - ANSYS Fluent coupling for one- and two-way particles-fluid coupling. Combined with the new thermal model, users can now analyze, among other things, the heat transfer between fluid and particles in Rocky-Fluent coupling, enlarging the range of processes that can be modeled using the Discrete Element Method (DEM).
Updated User Manual
This latest release of Rocky DEM also launches a newly designed topic-based format for displaying the user manual content. When compared to the previous PDF format, this more familiar Help platform provides easier navigation from the Contents tab, improved search functionality from the Search tab, better print and zoom options, and more.

Rocky DEM Software 3.11.5 - Release notes:

As with all new versions, this release includes fixes to various user-reported issues from the previous release, providing an overall more stable experience.



About Rocky DEM. ROCKY DEM allows precise prediction of the particle behavior of granular and liquid systems by analyzing media flows, energy absorption rates and particle breakage. Wherever large quantities of particles and bodies are set into motion in bulk, mixing, slipping or flow processes regardless of their size, shape, material or adhesion, ROCKY can help to understand and improve the processes.

These are, on the one hand, measures for optimizing the movement of the mass, for example to minimize material losses or to prevent or suppress dust formation. On the other hand, the results provide important information for efficiently designing peripheral products, for example to increase the service life of conveyor belts and other components.

ROCKY DEM optimizes, among other things, agitator mills, SAG mills, crushers and high-pressure grinding rollers, the particle spectrum ranges from small synthetic parts such as tablets to gravel.

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.

Rocky DEM provides decisive insight into granular flow behavior with accurate particle representation.
