Agriculture Equipment

Test your equipment using particle simulation and enhance the efficiency of your agricultural processes. Rocky DEM is used the world over to help companies optimize their bulk agricultural materials.


Rocky DEM provides the data you need to predict particle behavior in agricultural equipment.

Understand particle behavior with precision and accuracy. Rocky DEM also provides a unique tool for engineers and designers to reduce the negative impact of variability in the bulk flow characteristics of feedstock, which can help increase productivity.

Storage Silos

Couple Rocky DEM with Ansys mechanical and fluid tools to study silo issues related to particle segregation, blockages, motion, and equipment failure. Unique flexible-fiber particle shapes provide the key to accurate simulation.

  • Minimize segregation

    Study sifting segregation in detail during the silo-filling process to achieve a more efficient flow-pattern design.

  • Analyze the Structure

    Rocky DEM integrates seamlessly with Ansys Mechanical to predict if a design can withstand the pressures and stresses of siloed material.

  • Evaluate Different Materials

    Stay ahead of equipment failure. Rocky DEM evaluates how different material types, size distribution, and adhesion forces affect silo flow pattern.

  • Multi-GPU processing

    Leverage multi-GPU capabilities to handle huge cases with millions of particles.
