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.

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.

Once Enerkem identified that CFD-DEM was the right solution, the game changer was Rocky-DEM’s solver efficiency running on multi-GPUs. Our simulation problems have tens of millions of coarse-grains, and other DEM software took weeks, months, even a year to resolve. This is not a practical time frame. Rocky DEM enabled us to simulate a large-scale reactor in acceptable time. Months became weeks, weeks became days.

Our interest is understanding particle-flow behavior in biomass materials used to create bioenergy. We are one of the first laboratory teams to use the advanced shape models in Rocky DEM, exploring their suitability for modeling biomass particles and flow variability, within biomass handling equipment. We have already determined that Rocky DEM’s flexible fiber model is suitable for corn stover tissue, and we will use it to perform complicated simulation scenarios for flow and shear tests to identify particulate behavior.
