ROCKY is a powerful, 3D Discrete Element Modeling (DEM) program that quickly and accurately simulates the granular flow behaviour of different shaped and sized particles within a conveyor chute, mill, or other materials handling equipment.

Several capabilities set ROCKY apart from other DEM codes, including non-round particle shapes, the ability to simulate particle breakage without loss of mass or volume, the visualization of boundary surface reduction due to wear, and more.

Mining and manufacturing organizations all over the world are choosing ROCKY DEM software to evaluate their bulk material handling systems because ROCKY simulates granular flow quickly, accurately, and with more similarity to real-world conditions than ever before. With its ability to create realistic shapes that settle and compact just like actual particles, and its variable sticky and dust-like conditions, ROCKY can replicate nearly any type of material handling environment imaginable.

Key Features of ROCKY are:

  • NON-ROUND PARTICLES:ROCKY uses truly non-spherical particle models that behave like real-world particles, which produces more realistic results.
  • BREAKAGE SIMULATIONS: ROCKY simulates breakage by calculating the fracture of each particle based upon the energy generated from impact or friction.
  • GPU PROCESSING: ROCKY's new use of the GPU accelerates the computational workload, especially when processing simulations with many particles.
  • ROCKY AND ANSYS COUPLING: A particle-to-structure and particle-to-fluid interaction model is becoming more and more essential to solve realistic problems in the industry. The simplest model is to model a one-way coupling where the DEM solver (e.g. ROCKY) provides load-sets to be used in a structural analysis or CFD analysis tool (e.g, ANSYS). For a more complex problem, bi-directional exchange of information is necessary while both solvers (DEM and FEA/CFD) are calculating.
