Modeling of bulk and granular materials based on the discrete element method (DEM)
Altair EDEM

Altair EDEM is a high–performance software for modeling bulk and granular materials. The Altair EDEM solver is based on the discrete element method (DEM), which quickly and accurately models and analyzes the behavior of coal, mined ores, soils, fibers, grains, tablets, powders and more.

Altair EDEM modeling allows engineers to get an idea of how bulk and granular materials will interact with their equipment in various operating and process conditions. Altair EDEM can be used standalone or in combination with other CAE solutions.

Areas of application of Altair EDEM

Mining and construction industry

Side-turn loaders, excavators, backhoe loaders and truck bodies are designed for processing bulk materials, which can vary in shape: from large quarry rocks to cohesive soils, abrasive ores or loose granules. These materials and their interaction with machine parts have a strong impact on the performance of the equipment. Altair EDEM allows engineers to predict the behavior of bulk materials and identify the risk of clogging, spillage and areas prone to wear. Altair EDEM provides precise material loads that can be used in finite element analysis (FEA) and multibody dynamics (MBD) modeling to obtain optimal designs.

The agricultural sector

Tractors, combines and forage harvesters are designed to work with a variety of granular materials such as cereals, seeds and soil, the properties of which may vary depending on location and seasonal conditions. The variety of these materials can have a strong impact on machine performance. Altair EDEM allows you to predict the consumption of these materials and identify the risks of clogging, wear and damage to the crop. It can be combined with multi-body dynamics tools such as Altair MotionSolve (more details) to simulate the interaction between a crop machine and a tillage machine and predict the response of equipment to various materials.

Off-road vehicles

SUVs face some of the most difficult conditions in the world - from loose desert sand to gravel dirt roads, sticky muddy terrain. Altair EDEM allows you to realistically simulate various landscapes - from soft soil, dry sand to uneven gravel surfaces. Combined with multi-body dynamics (Altair MotionSolve), Altair EDEM provides greater realism in vehicle mobility modeling and allows engineers to predict the behavior and performance of tracked and wheeled vehicles in various conditions and study complex maneuvers that are not easy to reproduce in the physical world. This allows engineers to conduct a thorough "what if" analysis of the project early in the design cycle in order to increase reliability and reduce the costs associated with physical prototyping and testing.

Mining and processing of minerals

The performance and reliability of conveyor transfer devices and loading trays, regenerators, crushers and grinding mills is the most important factor determining the productivity of mines and factories. Altair EDEM allows engineers to understand the flow of rocks, ores, and coal through each segment of their equipment or operations. It is used to evaluate and verify the design characteristics of transfer chutes and solve key design problems such as leakage, clogging and wear. It is also used to optimize grinding equipment by predicting the impact of mill crusher geometry, ore characteristics and operating conditions on grinding efficiency, mill productivity and energy consumption.

Steel smelting

Iron ore, coal, pellets and sinter form the basis of the steelmaking process. Altair EDEM can be used to simulate a range of operations and processes that ensure efficient handling of these materials. This allows engineers to virtually study the operation of blast furnace loading devices and is used to minimize segregation during the loading of blast furnaces, optimize the distribution and dispersion of material, as well as predict areas of equipment wear. EDEM provides key information that would otherwise be impossible to obtain through experiments.It is a key tool to help improve steel quality, energy efficiency and blast furnace performance.

Pharmaceuticals, food and chemicals

Bulk materials are used in more than 70% of industrial processes either as raw materials or as an end product. The efficient handling and recycling of these materials is crucial for the profitable production of pharmaceuticals, food and other products. Altair EDEM models and analyzes the behavior of powders, tablets, capsules, granules, aggregates, etc. It is used to simulate a range of processes, including mixing, coating, mold filling, granulation, grinding and more. EDEM provides key information leading to process optimization, improved product quality, fewer physical prototypes, and cost savings. EDEM can be combined with Altair CFD™ to simulate complex particle-liquid systems such as fluidized beds, solid-liquid mixing, spray coating, drying and pneumatic transport.
