Heavy Equipment

Discover the benefits Discrete Element Method (DEM) simulations can offer the heavy equipment manufacturing industry as a powerful tool that uniquely simulates and analyzes the behavior of bulk materials.


Increase heavy-equipment production capacity and longevity by understanding how the materials it excavates, harvests, and transports affects composition and function. Rocky DEM embeds powerful capabilities that simulate and analyze complex bulk-material behavior, from flow to breakage to motion, in harsh environments and operating conditions.

Applications applications


Rocky DEM’s capabilities investigate complex granular flow and particle-equipment interaction, leading to a better understanding of how different materials affect excavator and bucket designs.

  • Analyze the Structure

    Coupled Rocky–Ansys Mechanical simulation accurately predicts stresses and deformations on equipment specific to the material being excavated.

  • Evaluate wear

    Increase equipment lifetime by analyzing how shear and impact forces affect surface.

  • Adhesion modeling

    Rocky DEM’s adhesion models predict excavation performance for different materials and environmental conditions.

  • Faster results

    Advanced computing methods and multi-GPU capabilities provide faster and better results.
