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 simulating 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 within the Brazilian company ESSS. Initially, the development of the product took place in relation to the tasks of mineral processing, with an orientation towards calculating the movement of particles in cylindrical mills and continuous transport systems. With the release of new versions, the capabilities of ROCKY have significantly expanded 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, taking into account different “flow” conditions, ROCKY can simulate the operation of almost any installation.

Joint calculations in ROCKY and ANSYS
ROCKY и 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 meshes.
