Altair EDEM™

Discrete Element Modeling (DEM) software

EDEM simulation of Powder Mixing in High Shear Granulator

The video presents how EDEM can be used to analyze the mixing efficiency within a High Shear Granulator filled with 10 million particles. In this example, the mixing process of two powders with different particle size is shown. EDEM allows to visualize mixing from different angles, color particles by velocity to see where particles stagnate and analyze the mixing effectiveness by showing the concentration of each type of particles in the mixer.

Use Cases

Using Altair Software for Process Manufacturing

Watch examples of applications of Altair EDEM in the pharmaceutical, food, chemicals and additive manufacturing industries.

EDEM software, powered by the Discrete Element Method (DEM), enables companies to accurately simulate and analyze the behavior of bulk solids, providing key information on processes otherwise difficult or sometimes impossible to measure. EDEM enables a detailed analysis and visualization of the flow of particles, from powders to tablets, through process segments and handling equipment and can promote both innovation in product design as well as reduce the need for physical prototypes and long product development cycles.

Use Cases

EDEM simulation of Wet Mixing - Liquid Transfer in a Drum Mixer

In this example, EDEM’s Application Programming Interface (API) can be used to introduce custom physics to the simulation, allowing particles to have a liquid content. Here, particles with a water content are added into a mixer containing powder. EDEM allows users to study the increase in water content over time and to analyze mixing efficiency.

Use Cases

Pin mills are widely used across many industries to comminute bulk solids like chemicals, sugar, herbicides and resins. In this video EDEM is used to simulate and analyze material size reduction in a pin mill, using the Tavares Breakage Model to accurately simulate breakage.

Use Cases

EDEM simulation of Die Filling for Pharmaceutical Powders

This video shows the analysis of the feed frame for the die filling process for pharmaceutical powders. EDEM allows the use of colors to differentiate powders by type, velocity and residence time. Additionally, the set-up of bins enables collecting, extracting and plotting the data, for further analysis. By simulating powders with different cohesiveness and varying other parameters such as the RPM, EDEM allows equipment and process optimization for any combination of powders.

Use Cases

EDEM simulation of Tablet Coating

The EDEM Application Programming Interface (API) is used to create custom contact models and properties to simulate tablet coating process. The video demonstrates how EDEM can be used as a predictive tool to perform virtual testing and investigate the effects of parameters like tablet shape or coating pan speed on the coating uniformity.

Use Cases

EDEM simulation of Tablet Compaction

In this video EDEM is used to simulate and analyze a tablet compaction process, using the Edinburgh Elasto-Plastic Adhesion contact model (EEPA) to capture the complex behavior of the powders. EDEM enables users to obtain key micro-mechanical information such as compression forces, stress and porosity and to predict tablet defects.

Use Cases

EDEM simulation of Hopper Discharge for Powders

This video shows the analysis of the hopper discharge process for powders. EDEM allows coloring the powders by layers, velocity and residence time. Additionally, the set-up of bins enables collecting, extracting and plotting data such as mass flow rate, for further analysis. By simulating powders with different cohesiveness and varying other parameters, EDEM allows specific equipment and process optimization for different powders.

Use Cases

EDEM simulation of Screw Auger handling Powders

This video compares the behavior of two different powders in a screw auger – one of the powders being highly cohesive and the other one free flowing. EDEM provides key insight into the discharge of the hopper, the compressive force acting on the powders, the mass flow rate and the power required to drive the screw blade.

Use Cases

EDEM simulation of Food processing Extruder

This video was part of a project with Micron, where EDEM was used to model a food processing extruder. Using EDEM software it was possible to simulate how the material turns into a solid under high compression at the extruder nozzle. In addition, key analysis was conducted on the system including material throughput through the nozzle and identifying the amount of material not discharged.

Use Cases

EDEM simulation of Powder Dosing Wheel in Additive Manufacturing

In this collaboration with The Barnes Group Advisors, EDEM has been used to get an insight into the functioning of the material delivery system used in an additive manufacturing printer. Two powders with different flowability were characterized and simulated to compare and analyze the differences in the dosing process. Some of the analysis conducted includes material agglomeration, mass flow rate and powder compression. EDEM can assist in obtaining an in-depth understanding of the additive manufacturing processes.

Use Cases

EDEM simulation of Powder Raking in Additive Manufacturing

This simulation models over 8 million particles of less than 0.3mm in size. Large amounts of tiny particles are common in Additive Manufacturing applications. This video shows powder raking and how EDEM tools can be used to analyze voidage, particle orientation and number of contacts at different time steps. Similar simulations can guide the design and optimization of the powder rake and its speed.
