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.

Sub-Zero uses many different physics tools, and Rocky DEM fits like a glove into our existing portfolio. Combining Rocky DEM with CFD provides real insight on understanding a specific speck of dust on a specific surface within a certain geometry. Our task is to create a design around that reality, developing a refrigerator heat exchanger that is robust to dust accumulation.”

Implementing Rocky DEM into our portfolio allows us to be a bit braver when it comes to design concepts, because we will be able to test many more ideas virtually to find the one that works best. An added benefit is that simulation knowledge about how the product and system work together will be saved in a digital library, which can trigger new ideas and better products."

ROCKY DEM is helping us to improve various processes. The use of simulation tools can quantify the design improvements and gains; this is advantageous because mining uses large equipment that without computer simulation can cost millions for prototype development and testing. Accurate simulation results can advocate for necessary changes and updates, with the assurance of a return on investment.”

"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.”
