EDEM

EDEM is the world´s first general-purpose CAE tool to use state-of-the-art discrete element modeling technology for the simulation and analysis of particle handling and manufacturing operations. Its modeling environment enables you to handle the complexity of real industrial processes, gives you the flexibility to incorporate your own physical models and the ability to couple with other CAE tools.

With EDEM you can quickly and easily create a parameterized model of your granular solids system using imported CAD models of real particles to obtain an accurate representation of their shape. Add the mechanical, material and other physical properites to form your model particles. These can be stored in a library allowing you to build a collection specific to your processes.

EDEM manages information about each individual particle (mass, temperature, velocity and so on) and the forces acting on it. It can also take into account the particle´s shape, rather than assuming that all particles are spherical. With EDEM´s powerful post-processing tools you can visualize and graph any combination of variables.

EDEM is developed by DEM Solutions, a global leader in discrete element modeling software.

Benefits

Customers in industries such as pharmaceutical, chemical, mineral and materials processing as well as oil & gas production, agricultural and construction and geo-technical engineering use EDEM to design, develop and test products.Thus processing faster and more accuratel results than was previously possible and also reducing their development costs and time to market. EDEM enables engineers to better understand the complex interaction between material properties, equipment design, and operating conditions. Much of this information was not previously available and is leading to innovation in product design and higher and more consistent product quality.
