Rocky

Next generation DEM Particle Simulator

ROCKY is a 3D Discrete Element Method (DEM) code that simulates the granular flow behavior of different shaped and sized particles, with varying levels of moisture (adhesion), friction and impact restitution along the handling chain of the granular material itself.
Therefore ROCKY is used all over the world by manufacturing and mining companies, to quickly and accurately analyze their bulk material handling systems. The software consists of a single working environment which is accessed by a simple and user-friendly graphical interface, which allows to create the mathematical model, to run the simulation and to evaluate all results necessary for the analysis.

Why ROCKY is different apart from other DEM codes?
ROCKY is the only commercial code that uses an accurate particle shape representation (not cluster of spheres), advanced breakage and fragmentation models, visualization of boundary surface reduction due to wear, complex geometry motion, double precision solver that uses Share-parallel memory with CPU or Multi GPU, extensive code validation and calibration. ROCKY is fully integrated with ANSYS Workbench with Structural and Fluid analysis coupling.

ROCKY

Fluidized bed simulation (2-way coupling with ANSYS Fluent)

Rocky DEM accurately replicates many types of materials — such as ore, grain, plastic, and metal — and can do so with varying levels of moisture (adhesion).

 

With Rocky DEM you can mix and match different shape, size, and adhesion combinations to create your own unique particle set.
