Rocky DEM Overview

Rocky DEM is a powerful, 3D Discrete Element Modeling (DEM) program that quickly and accurately simulates the granular flow behavior of different shaped and sized particles within a conveyor chute, mill, or other materials handling equipment.

Several capabilities set Rocky DEM apart from other DEM codes, including its Multi-GPU processing capabilities, truly non-round particle shapes, the ability to simulate particle breakage without loss of mass or volume, the visualization of boundary surface reduction due to wear, and more.

Mining and manufacturing organizations all over the world are choosing Rocky DEM software to evaluate their bulk material handling systems because Rocky DEM simulates granular flow quickly, accurately, and with more similarity to real-world conditions than ever before. With its ability to create realistic shapes that settle and compact just like actual particles, and its variable sticky and dust-like conditions, Rocky DEM can replicate nearly any type of material handling environment imaginable.

The streamlined calculations and Multi-GPU processing capabilities included within Rocky DEM produce faster and more accurate results when compared to other DEM products. Rocky DEM can simulate more than tens of millions of particles in nearly limitless size and shape distributions from rocks to grain, metal to plastic, and beyond.

ROCKY is 3D discrete element modeling (DEM) software which can simulate the motion and effect of a large number of small particles, their interactions with each other and boundary surfaces. ROCKY DEM includes non-spherical particle simulation, boundary wear and breakage modeling. ROCKY DEM utilize multi GPU solving technologies to reduce computational effort required for large simulations.

    • 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.

      - Francesco Pietra, University of Pretoria

    • 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.
