Ansys Rocky

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

  • Simulate Real-Scale Experiments

    Rocky'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'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 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.

Rocky DEM - Multi-GPU Solver Capabilities

Multi-GPU Solver Capabilities

Only in Rockycan 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.
 
 
Rocky DEM - Multiple Particle Shapes

Multiple Particle Shapes

Rocky allows modeling of accurate particle shapes which includes custom 3D bodies, 2D shells and fibers which can be made rigid or flexible.
 
 
 
 
Rocky DEM - Complex and free-body motion

Complex and free-body motion

Enable your equipment components to move freely in response to forces such as particle contacts, gravity, and more.
 
 
 
Rocky DEM - Breakage Models

Breakage Models

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

Fluid Flow Modeling

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

Particle and Contact Energy Spectra

Rocky enables you to collect and analyze energy spectra as a useful alternative to the often computationally intensive breakage modeling solutions.
 
 
Rocky DEM - 3D Surface Wear Modification

3D Surface Wear Modification

Rocky 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.
 
 
 
Rocky DEM - Collision Statistics

Collision Statistics

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

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.
 
 
Rocky DEM - Fully Ansys Integrated

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.
