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.

"The highlight of the Rocky DEM software is certainly its speed and realistic particle shapes. For us, being able to simulate the exact number of particles in the exact same size distributions and shape representations that we have in our experimental studies is the primary benefit to using Rocky DEM.”
