Process Equipment

Explore new possibilities to enhance your processing efficiency. Rocky DEM is being used to improve everything from drugs to food, and from specialty chemicals to biofuels.


  • Rocky DEM is the most powerful solution for companies in the food, pharmaceutical and chemical industries to optimize the performance of their processing equipment.
  • Rocky DEM enables processing industries the world over to accurately simulate and analyze the behavior of bulk solids, boosting their performance.

Application 1: Coating

Simulate real-scale equipment by using custom polyhedral, shell and fibers particles to model coating of pills, tablets, the seasoning of chips and nuts and the homogeneous covering of chocolate and candies.

  • Polyhedral elements: Predict the dynamic behavior of a bulk material accurately. No more artificially bumpy surfaces that can significantly affect particle dynamics.
  • Contact statistics: Improve your design in order to reduce breakage by analyzing contact statistic data.
  • CFD coupling: Run coupled simulations and take into account the hot/cold air flow in the coating process.

Application 2: Drying and Heat Exchange

Rocky DEM particle simulation is the best solution for simulating the conductive and convective heat exchange and drying process of bulk materials.

  • Rocky-Fluent coupling:  Rocky DEM integration with ANSYS Fluent in order to analyze the convective heat transfer between particle and fluid.
  • True physical representations: Increase the accuracy of your simulation by using realistic particle shapes.
  • Multi-GPU processing: Make use of the multi-GPU capabilities to handle huge cases with millions of particles.

Application 3: Controlling Discharge

Rocky DEM is able to simulate a real bulk flow regulation, helping to control the flow rate to a level more suited to the process.

  • Improve the hopper discharge: Rocky DEM is widely used to evaluate the discharge flow pattern of hoppers helping engineers to eliminate the stagnant zone, mitigating problems related to degrading material.
  • Evaluate your feeder and valves: Optimize your valve or feeder designs and get a uniform drawdown from the hopper.
  • Realistic particle shapes: Predict accurately the dynamic behavior of a bulk material by using polyhedral or shell particles.

Application 4: Packaging process

Evaluate and improve the packaging process with custom imported particles shapes simulating scenarios such as snack chips being filled in a bag.

  • Real-world simulations: Perform virtual experiments on your product lines and simulate the world in real life, with true physical representations.
  • Faster results: Discover how advanced computing methods and multi-GPU capabilities can provide you with faster and better results.

Application 5: Mixing Equipment

Rocky DEM simulates with precision and accuracy the efficiency of your mixing and blending equipment, increasing batch sizes and reducing blend times and segregation.

  • More productivity: Rocky DEM helps to optimize the mixing device design in order to reduce blending time, increasing productivity.
  • Upscale your equipment: Use DEM to evaluate the best upscaling strategy, from lab to commercial scale.
  • Add complex motions: Simulate complex, combined geometry motions using Rocky DEM fully integrated motion kernel.

  • I would like to hereby express my vote of confidence in Qfinsoft, in their ability to service and provide a strong support to us as a company.  We have been a customer of Qfinsoft for over a year and I am pleased to compliment them on their impeccable service offered to us thus far

    - Nico Gunther, Powertech Transformers

  • Since the introduction of ANSYS, more students are using first principles and FEA to validate their designs. This year, more than 60% of the projects were using FEA as a standard approach for numerical calculation. This number shows the huge impact ANSYS, had on University of Pretoria. FEA is not anymore a specialised tool for few users but a standard engineering tool easily integrated in the design process.

  • For their consulting, training and technical support, Qfinsoft (Pty) Ltd must be the first choice of any firm looking for CAE experts

    - Prof G Akdogan, Process Engineering, University of Stellenbosch

  • At Aerospace, we have successfully used the ANSYS suite of tools to design high-performance gas turbine engines. Throughout this program, Qfinsoft provided valuable support and assistance to accelerate the development of our models. Their accessibility, short-turn around times and willingness to go beyond what is expected make them an effective partner on our projects.
