Key Use Cases
What is Rocky DEM
Discrete Element Method — the physics of bulk solids
Rocky DEM (Discrete Element Method) models every individual particle separately — tracking its position, velocity, rotation, and all contact forces with neighbouring particles and equipment surfaces. Unlike CFD which treats material as a continuum, DEM captures the fundamentally discrete nature of granular matter: segregation, avalanching, jamming, and impact wear.
Rocky DEM was developed by ESSS and is part of the ANSYS partner ecosystem. CADFEM Ukraine is the official Rocky DEM distributor in Ukraine — providing licenses, English-language DEM training, simulation consulting, and GPU configuration support for mining, metallurgy, chemical, and energy companies.
Realistic particle shape — the key differentiator
Rocky DEM models true particle morphology: polyhedral shapes imported from STL/STEP, superquadric parametric shapes, and concave particles (chains, stars, spirals). Realistic shape directly impacts angle of repose, bulk density, segregation, and wear prediction accuracy.
Native GPU acceleration (NVIDIA CUDA)
Rocky DEM is built on a native GPU architecture — all DEM computations run on NVIDIA CUDA in parallel. Up to 100 million particles on a single NVIDIA A100 GPU. Industrial-scale problems in hours, not weeks.
CFD-DEM: two-way coupling with ANSYS Fluent
Bidirectional Rocky DEM + ANSYS Fluent coupling: particles affect the gas/liquid flow, and the flow affects particle trajectories. Used for fluidized beds, pneumatic conveying, hydrotransport of slurry, and cyclone separators.
Equipment wear prediction
Rocky DEM computes equipment wear using Archard (abrasive sliding wear) and Energy Wear (impact wear) models — generating wear maps on equipment surfaces as a function of simulation time. Predict liner and chute life before physical testing.

Pricing
How much does Rocky DEM cost?
Pricing depends on license type (lease or perpetual), number of GPUs licensed, and whether CFD-DEM (Rocky + Fluent) or FEM-DEM (Rocky + Mechanical) coupling modules are included. Submit a request — we prepare individual quotes within one business day.
GPU requirements
What GPU hardware does Rocky DEM require?
Rocky DEM requires an NVIDIA GPU with Pascal architecture or newer (GTX 1080 and above). For engineering workstations: NVIDIA RTX A4000 or A5000 (16 GB VRAM) is recommended. For server-grade or large industrial models: NVIDIA A100 (40/80 GB VRAM). Rocky DEM also runs in CPU-only mode for small models and testing.
ANSYS coupling
Does Rocky DEM require ANSYS Fluent or Mechanical?
Rocky DEM runs as a standalone DEM solver. For CFD-DEM analysis (gas/liquid-particle interaction), ANSYS Fluent is additionally required. For FEM-DEM wear analysis (structural deformation due to particle impact), ANSYS Mechanical is required. Contact CADFEM Ukraine for bundle pricing of Rocky + Fluent or Rocky + Mechanical.

+38 (050) 454-37-54What is Rocky DEM and how does it differ from CFD (ANSYS Fluent)?
+
Rocky DEM (Discrete Element Method) models every individual particle — its position, velocity, and contact forces with other particles and equipment surfaces. CFD (Fluent) models fluids as a continuum using the Navier-Stokes equations. For bulk solids (ore, grain, powder, pellets), DEM is far more accurate than continuum models: it predicts segregation, flow patterns, angle of repose, and wear with physical fidelity. CFD and DEM are complementary — Rocky DEM + Fluent CFD-DEM coupling models both the particles and the carrying gas or liquid simultaneously.
Why is Rocky DEM faster than other DEM software?
+
Rocky DEM is built on a native GPU architecture (NVIDIA CUDA) — all DEM computations are parallelized on the GPU from the ground up. This gives 10–50× speedup compared to CPU-based DEM codes. On a single NVIDIA A100 (80 GB), Rocky DEM can simulate up to 100 million particles simultaneously. Most competing DEM software treats GPU as an optional add-on rather than the primary compute engine — leading to lower practical speedup.
What particle shapes does Rocky DEM support?
+
Rocky DEM supports the widest range of particle shapes in the industry: spheres (baseline); superquadrics — parametric shapes from sphere to cube to cylinder; polyhedral particles — imported directly from STL or STEP files for exact replication of ore fragment morphology; concave (non-convex) particles — chains, spirals, star-shaped granules. Realistic particle shape is critical for accurate prediction of angle of repose, bulk density, segregation, and wear. Round spheres systematically underpredict wall impact forces compared to angular ore.
What is CFD-DEM and when is it needed?
+
CFD-DEM is the bidirectional coupling of Rocky DEM (particles) with ANSYS Fluent (gas or liquid): Fluent computes the velocity and pressure field of the carrier phase; Rocky computes particle trajectories with drag, lift, and added mass forces from the Fluent flow field; particle presence feeds back into Fluent as momentum source terms. CFD-DEM is needed when the fluid and particles mutually influence each other: fluidized bed reactors, pneumatic conveying in pipes, slurry hydrotransport, cyclone separators, and CFB boilers.
How does Rocky DEM predict equipment wear?
+
Rocky DEM computes wear on equipment surfaces using: Archard wear model — abrasive wear proportional to the sliding contact work (tangential force × sliding distance); Energy Wear model — impact wear proportional to the normal impact energy. At every time step, wear is accumulated on each surface element, producing a wear depth map as a function of simulation time. This predicts which regions of a mill liner, chute, or crusher concave wear fastest — enabling targeted material selection and geometry optimization before physical testing.
Does CADFEM Ukraine provide Rocky DEM support in English for mining and chemical companies?
+
Yes. CADFEM Ukraine provides all Rocky DEM services in English: official license procurement, GPU setup support, technical support, DEM simulation consulting, and training. We support international mining and chemical companies operating in Ukraine, Ukrainian producers exporting engineering services, and process engineering teams requiring DEM analysis reports in English.
