ROCKY is an effective software for simulating granular media by the method of discrete elements (DEM or DEM - Discrete Element Method), allows you to quickly and most realistically simulate the behavior of a flow of particles of bulk material with the required properties in any process and apparatus.

ROCKY is a state-of-the-art software for the simulation of technological processes with bulk materials and related equipment. The software 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 as it moves along conveyor lines, vibrating screens, mills, crushers and other types of processing and transport equipment. ...
The ROCKY software product was created on the basis of 20 years of experience in the development of calculation methods using DEM technologies at Granular Dynamics International LLC, a division of Conveyor Dynamics, Inc. Further product development will be carried out by 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, the calculation and visualization of abrasive wear of the working surfaces of equipment, the calculation of air flows arising from the movement of particles of bulk material during transportation, and much more.
ROCKY differs from other software solutions using the DEM method primarily in the ability to use realistic non-spherical particles, simulate their destruction without losing mass and volume, and calculate and visualize abrasive wear of the working surfaces of equipment elements. With the ability to create realistic particle shapes that behave like real particles, ROCKY can simulate virtually any installation under varying flow conditions.
• Efficient computing;
• Double precision calculations (using the appropriate GPU function);
• Wide range of particle size distribution;
• Non-spherical particles;
• Consideration of the rheology of dry and wet materials;
• Calculation and three-dimensional visualization of abrasive wear of surfaces;
• Setting the rotation, translational and vibration movement of equipment elements;
• Simple import of 3D CAD geometric models, clear definition of initial data and boundary conditions of the calculation;
• Integration with ANSYS finite element solvers;
• Management of animation of simulation results and creation of panoramic video reports.
ROCKY is a unique software package that can be configured according to the requirements of the customer company. The ESSS team will ensure that the program code is modified according 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;
- Geometric model and particle force data can be saved and transferred to a finite element analysis (FEM) system
Joint calculations in ROCKY and ANSYS
Bulk materials have been widely used and processed in various industries for centuries. However, there is still a lack of accurate information about their behavior in various conditions. In some cases, bulk materials behave as discrete solids, in others as liquids, or even compressively as gases.
There is a growing need to create a reliable predictive model of the behavior of bulk materials, taking into account the impact on equipment elements, thereby ensuring the solution of design problems during the modernization or creation of new innovative equipment.
The simplest case of particle-to-structure interaction (PSI) involves the transmission from a DEM solver (such as Rocky) of a dataset of force loads from particles of bulk material to structural members. The ANSYS solver (or other FEM solver) calculates the response of a structure to the force action of a particle flow. ROCKY contains a fast and accurate algorithm for performing joint DEM and FEM calculations for mismatched computational grids.
