Little P.Eng. for Discrete Element Modeling (DEM) Services

--

In a world driven by technological advancements, the ability to understand granular systems at a particle level has never been more essential. This precise understanding has been made possible through a computational technique known as Discrete Element Modeling (DEM). While many entities offer DEM services, Little P.Eng. has carved a niche for itself as a front-runner in this specialized domain.

Understanding Discrete Element Modeling (DEM)

Before diving into the specifics of Little P.Eng.’s offerings, it’s essential to demystify DEM:

DEM is Calculation-based Modeling: At the heart of DEM is mathematics. This method uses precise calculations to predict the behavior of individual particles within a system. By doing so, it can accurately predict the interactions and outcomes when these particles are subjected to various conditions.

DEM Allows for Visualizing Results: One of the standout features of DEM is its ability to provide visual results. Users can observe:

  • Particle Velocity: Understand the speed and direction of individual particles.
  • Forces: This includes shear (parallel to the surface) and normal (perpendicular to the surface) forces that the particles experience.
  • Moments: This refers to the bending and torsional (twisting) moments affecting the particles.
  • Acceleration and Material Scatter: Track how quickly particles move and the variations in their dispersion patterns.

DEM: More than just Flow Simulation: While DEM is instrumental in predicting the flow of bulk materials, its capabilities extend beyond this. It plays a crucial role in understanding:

  • Wear Patterns: Predict how equipment will fare over time by simulating particle interaction and the resultant wear.
  • Mixing: Understand how different particles mix, which is vital in industries like pharmaceuticals and food production.
  • Center Loading: This refers to the loading pattern where materials concentrate towards the center, crucial in industries like construction.

DEM Programs: The Power Behind the Predictions

Any tool is only as good as the software powering it. When it comes to DEM, numerous programs can be used to perform this intricate modeling:

  1. EDEM: A market leader, renowned for its comprehensive modeling capabilities.
  2. PFC (Particle Flow Code): Known for its versatility, offering both 2D and 3D simulations.
  3. LIGGGHTS: An open-source powerhouse that’s both versatile and widely accepted.
  4. Rocky DEM: Its strength lies in simulating realistic particle shapes, crucial for specific industries.
  5. Yade: An open-source tool prized for its extensibility.
  6. Abaqus: A multi-faceted software that, beyond its renowned finite element analysis, offers DEM capabilities.
  7. Ansys Rocky: Building on the Ansys platform’s strengths, it focuses on granular flow simulations.
  8. Barracuda Virtual Reactor: Ideal for energy sector applications, especially particle reactions.

Also there are some open sources:

  • Kratos Multiphysics is developed by CIMNE (International Center for Numerical Methods in Engineering) in Barcelona and covers all kinds of numerical simulations, including DEM/PEM and DEM/PEFM-FEM coupling.
  • YadeDEM is a DEM package that is specifically designed for geomechanics.
  • Woo is a fork of YadeDEM with a strong focus on parallel computing and portability.
  • LAMMPS is a general purpose DEM/PEM.
  • LIGGGHTS is a general purpose DEM software that includes heat transfer simulations and is based on LAMMPS.
  • ESyS Particle is developed at the University of Queensland, Australia, with a focus on geoscientic/geotechnical applications.
  • GranOO is a general purpose DEM.
  • MercuryDPM is a general purpose Discrete Particle Method (DPM) software.
