Today, major goals of the worlds mining companies include reducing operating costs, optimizing processes, and improving the reliability of equipment. One of the most effective ways to achieve these goals is to integrate powerful simulation tools, such as ANSYS and ROCKY, into the equipment design process.

A flexible, hierarchical interface makes coupling ROCKY with ANSYS simple to set up and carry out. This newest release includes a 2-way transferring feature of loading data that is compatible with most ANSYS products, including ANSYS/Mechanical and ANSYS/LS-Dyna. For engineers using other FEM products, loading data can be imported to or exported from the most popular codes. On the Computational Fluid Dynamics (CFD) side, ROCKY still includes 1-way coupling with ANSYS/Fluent, enabling the particle forces data from ROCKY to be analyzed by ANSYS.

Moving the Limits Forward for Bulk Material Handling Equipment Design and Analysis

ROCKY and ANSYS

Dynamic Efficiency & Vibration Analysis

Structural Analysis & Design

ANSYS has the industrys strongest multiphysics portfolio. As a result, engineers can leverage systems-level analysis to make intelligent trade-offs in a low-risk, cost-effective virtual design environment. ANSYS provides a complete set of elements behavior, material models, and equation solvers for a wide range of engineering problems. From structural analysis to fluid flow, thermal evaluations to coupled-physics capabilities, ANSYS has the calculations acoustic, piezoelectric, thermal-structural, fluid-structural, magnetic-structural and thermoelectric, to name a few to analyze nearly any structure.

ROCKY is used to evaluate the particle flow within bulk material handling systems. It has a powerful 3D Discrete Element Modeling (DEM) solver developed jointly by ESSS (Engineering Simulation Scientific Software Ltda.) and GDI (Granular Dynamics International, LLC.) capable of quickly and accurately simulating multi-shaped particle behavior within a conveyor chute, mill, or nearly any other material handling equipment imaginable.

WHY CHOOSE ROCKY?

Mining and manufacturing organizations all over the world are choosing ROCKY to evaluate their bulk material handling systems because ROCKY is:

FAST & ACCURATE: Using streamlined calculations and double precision processing, on both CPU and GPU processors, ROCKY provides you with accurate results quicker than ever before. Given that each particle is calculated as one item, as compared to sphere clumps which are calculated as many individual spheres stuck together, it takes less time to calculate a ROCKY simulation, reducing the overall processing time dramatically.

EASY TO USE: A flexible, hierarchical interface, customizable parameters, and programmable scripts and macros make ROCKY simulations simple to set up, run, and iterate upon. ROCKY can also easily import CAD geometries and export data to the most popular Finite Element Analysis (FEA) programs available in the market, including direct integration with the ANSYS/Structural, ANSYS/Mechanical and ANSYS/LS-Dyna packages.

AFFORDABLE: ROCKY is priced competitively and gives you the highest performing DEM functionality for the investment.

CUSTOMIZABLE: If out-of-the-box ROCKY does not meet your organizations unique needs, ESSS developers can tailor the ROCKY code to match your specific requirements.

REALISTIC: ROCKY simulates more than 5 million particles in nearly limitless shapes and size distributions. Shapes like faceted polyhedrons, briquettes, and cylinders compact, settle, and behave just like real-world particles. Coupled with variable wet, dry, and dust-like properties, ROCKY is capable of giving you more realistic results.
