ROCKY - effective software for modeling granular media by the method of discrete elements (MDE or DEM - Discrete Element Method), allows you to quickly and as realistic as possible to simulate the behavior of the flow of particles of granular material with the necessary properties in any processes and devices.


ROCKY is a modern software for modeling processes with bulk materials and related equipment. The software product uses the Discrete Element Method (DEM), which allows you to quickly and accurately calculate the behavior of a stream of particles of various shapes and sizes when moving along conveyor lines, on vibrating screens, in mills, crushers and other types of processing and transport equipment .
The ROCKY software product was created based on 20 years of experience in developing computational techniques using DEM technologies at Granular Dynamics International LLC, a division of Conveyor Dynamics, Inc. Further product development will be carried out within the Brazilian company ESSS. Initially, the development of the product took place in relation to the tasks of mineral processing, with a focus on calculating the movement of particles in cylindrical mills and continuous transport systems. With the release of new versions, the capabilities of ROCKY have expanded significantly, and allow you to perform a wider range of tasks, for example, calculating and visualizing the abrasive wear of work surfaces of equipment, calculating air flows arising from the movement of particles of bulk material during transportation, and much more.

Customization
ROCKY is a unique software package that can be configured to the requirements of the customer company. The ESSS team will ensure that the program code is customized to your specific requirements.
Integration and Data Transfer
- The Rocky software package allows you to import XGL, STL and DXF files that can be exported from CAD programs, such as Autodesk Inventor or AutoCAD;
- Data on the geometric model and force action of particles can be stored and transferred to the finite element analysis system (FEM)
Joint calculations in ROCKY and ANSYS
ROCKY and ANSYS
Bulk materials are widely used and processed in various industries for centuries. However, there is still a shortage of accurate information about their behavior in various conditions. In some cases, bulk materials behave as discrete solids, in others as liquids, or even undergo compression effects like gases.
There is a growing need to create a reliable prognostic model of the behavior of bulk materials, taking into account the impact on equipment elements, thereby ensuring the solution of design problems when upgrading or creating new innovative equipment.
The simplest case of particle-to-structure interaction (PSI) involves the transfer from a DEM solver (for example, Rocky) of a set of data on force loads from particles of bulk material onto structural members. ANSYS solver (or other FEM solver) provides a calculation of the response of a structure to the force impact of a particle stream. ROCKY contains a fast and accurate algorithm for performing joint calculations using DEM and FEM methods for mismatched computational grids.
