Particle simulation
where shapes do matter

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.

“With Rocky DEM’s breakage model, we were able to discover how little lump breakage was occurring and what was needed to break the lumps up sufficiently for the iron ore to pass through during the tippler operation. These are key insights that will help optimize the equipment to reduce blockages and make sure the material moves more effectively and efficiently.”

Now that we know we can rely on our simulation results, Rocky DEM has improved our whole design process. We can do more runs, study more-complex problems, and get results faster. Before we added Rescale, we had to wait until our local hardware finished its run to start the next project. Now we have extra compute capacity when we need it. The combination of Rocky and Rescale gives us the confidence that the design is really valid, and we don’t need to rely on prototype build and tests as much as before.
