Rocky DEM Inc.

Particle simulation where shapes do matter. Rocky DEM quickly and accurately simulates the flow behavior of bulk materials with complex particle shapes and size distributions.

  • Simulate Real-Scale Experiments

    Rocky DEM’s high-performance computing (HPC) abilities can simulate a large number of real-sized and real-shaped particles faster and with less memory usage.

  • Model Realistic Materials

    Modify a default shape, scan a real 3D object, or custom design your own shape and import it. Then define the behavior to be rigid or flexible, sticky or dry, breakable and more.

  • Solve Unique Problems

    Rocky DEM’s representation of application-specific particle shapes is becoming essential to the successful engineering of bulk materials handling equipment.


Leverage your industry

Get access to the key features for optimization of industrial equipment and processes.

Several features set Rocky DEM apart from other particle simulation software: its multi-GPU processing capabilities, truly non-round particle shapes, ability to simulate particle breakage without loss of mass or volume, visualization of boundary surface reduction due to wear, and more.

Multi-GPU Solver Capabilities

Rocky DEM - Multi-GPU Solver Capabilities
Only in Rocky DEM can you combine the processing power of several GPU cards to accelerate your simulations, enabling you to work with higher volumes of data in less time.

Multiple Particle Shapes

Rocky DEM - Multiple Particle Shapes
Rocky DEM allows modeling of accurate particle shapes which includes custom 3D bodies, 2D shells and fibers which can be made rigid or flexible.

Complex and free-body motion

Rocky DEM - Complex and free-body motion
Enable your equipment components to move freely in response to forces such as particle contacts, gravity, and more.

Breakage Models

Rocky DEM - Breakage Models
Currently, two kinds of breakage models are available in Rocky DEM: The Ab-T10 model and the Tavares model. Both models preserve both mass and volume.

Fluid Flow Modeling

Rocky DEM - Fluid Flow Modeling
In Rocky DEM, there are four unique methods for simulating the interaction between particles and the surrounding fluids (air, water, dust, etc.), known more commonly as CFD.

Particle and Contact Energy Spectra

Rocky DEM - Particle and Contact Energy Spectra
Rocky DEM enables you to collect and analyze energy spectra as a useful alternative to the often computationally intensive breakage modeling solutions.

3D Surface Wear Modification

Rocky DEM - 3D Surface Wear Modification
Rocky DEM also can be used also as a tool for the preparation of abrasive wear of solid surfaces and there are two major ways you can use Rocky DEM.

Collision Statistics

Rocky DEM - Collision Statistics
The visualization of collision statistics is a key feature in Rocky DEM. During the simulation, relevant collision data is stored between two consecutive output time levels.

Thermal Modeling

Rocky DEM - Thermal Modeling
If you want to observe how particles are affected by temperature changes brought on by the heating or cooling of other items around it, you may set up your simulation to model thermal properties.

Fully Ansys Integrated

Rocky DEM - Fully Ansys Integrated
Fully integrated with Ansys Workbench (CFD and FEA). Includes both one-way and two-way coupling abilities with Ansys Fluent providing physically consistent and accurate results.
