Get StartedThis powerful 3D Discrete Element Modeling program allows you to model particles with different shapes and sizes within materials handling equipment such as a conveyor chute or a mill.
Rocky DEM Applications
Mining & Metal
Discover a revolutionary way to enhance mining and metallurgical processes. Compare design modifications, replicate changes to production or environmental conditions by simulating coherent flow structures, equipment, and liner wear, mixing efficiency, and more.
Pharmaceutical, Agricultural & Food
The accurate shape representation and fragmentation models found in Rocky DEM can be used to evaluate the behavior of tablets, pills, snack chips, and more inside various kinds of screening, sorting, and mixing equipment.
Other Industries
Rocky DEM’s integration with CFD and FEA enlarges the range of industrial processes that can be modeled using DEM. Learn how companies just like yours have found solutions, resolved problems, and reached success with Rocky DEM.
Non-Round Particles
Rocky DEM uses truly non-spherical particle models that behave like real-world particles, which produces more realistic results.
Non-linearities
Rocky DEM simulates breakage by calculating the fracture of each particle based upon the energy generated from impact or friction.
Breakage Simulation
Rocky DEM simulates breakage by calculating the fracture of each particle based upon the energy generated from impact or friction.
GPU & Multi-GPU Processing
Rocky DEM’s unique ability of utilizing one or more GPU cards on the same motherboard greatly speeds up the computational time and allows for large-scale simulations involving tens of millions of particles.
What makes Rocky DEM unique?
The only commercial DEM code with:
- First ever multi-GPU solver capabilities, featuring cutting-edge shared-parallel-memory technology
- Accurate, non-round polyhedral particle shape representations
- Advanced breakage and flexible particle models
- Fully integrated with ANSYS Workbench (CFD and FEA)
- Integrated post-processing features customized for design engineers
- Best-in-class technical support and customer service solutions
With unprecedented similarity to real-world conditions, Rocky DEM quickly and accurately simulates granular flow. More and more mining and manufacturing organizations the world over are choosing Rocky Dem to analyze their bulk material handling systems. Rocky creates variable dust-like and sticky conditions, and uses realistic shapes that behave, settle, and compact exactly like actual particles. Nearly any type of material handling environment can be replicated with Rocky.
Rocky DEM FAQs
Yes. Any particles modeled in Rocky DEM can have different friction coefficients, or other material properties custom-defined within Rocky.
Rocky DEM can model solids, shells, flexible fibers and more. Virtually any shape or size 3D volumetric shape which can be imported in an STL format can be used as particle for bulk modeling and particle interactions within Rocky DEM.
Yes. Rocky DEM is tightly integrated with Ansys tools and can also provide 1-way coupling to other 3rd party FEA or CFD analysis systems.
Yes. Rocky DEM has its own proprietary solver technology and can also provide fully bundled or separate Pre and Post processing capabilities.
Yes! Rocky DEM provides solving on 2 CPU cores out of box but can enable scaling to a virtually unlimited count of CPU or GPU (recommended*) cores with associated licensing.
Rocky DEM provides solving on 2 CPU cores out of box. There are also CPU and GPU “packs” for multi-core processing. Because each model and hardware/software configuration is different, we recommend talking to our sales and technical personnel.
Yes! There are a number of sample files that help get you acclimated with the GUI and workflow.
Unlimited! As much as you have time and hardware to support. The greatest limiting factor in terms of particle count is solve time, which varies with each model and hardware configuration.
Run the following procedure on each system that you have designated to be a license server.
