Particle Simulation: Rocky Discrete Element Modeling (DEM)

Simulate granular flow behavior accurately and quickly with Rocky DEM.

Discrete Element Modeling Software

This 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.

Reduced-Order Models (ROMs)

Large-scale design exploration for design optimization and verification is made possible by seamless interaction with Ansys optiSLang, which also offers model calibration. Furthermore, users of Rocky can now create reduced-order models (ROMs) for their process simulations in order to develop digital twins in Ansys Twin Builder and on a range of software and hardware platforms.

Enhanced Multi-CPU and Multi-GPU

In the most recent Rocky DEM 4.5 Update, all apps’ performance and scalability were enhanced by multi-CPU and multi-GPU. Performance studies conducted on this new edition compared it favorably to earlier versions, with improvements ranging from 50% to 1000%, depending on the type of application.

Expanded CFD Capabilities

A wider variety of particle-fluid applications, as well as solutions for flows when particles are much larger than CFD mesh, are now included in the expanded CFD-DEM capability, all in a well-integrated workflow with Ansys Fluent.

Simulate Granular Particle Behavior

 

More than 90% of all goods we consume were, at some point during their lifecycle, in the particulate form. Gaining insight into the manufacturing processes of particles would enable engineers to reduce waste, and improve product quality and durability.  This is why having a robust particle simulation software with apposite modeling capabilities is a must-have to stay competitive in the current market.

Rocky DEM | Practical Application in Particle Simulation

 

 

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.

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.

 

 

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.

 

 

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’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.
