Particle simulation

DEM simulation

With DEM simulations, complex interactions between the particle flow and the components can be represented. This leads to a better understanding of the effects of different materials on the design and the apparatus. If fluid flow is significantly involved in this process, the particle simulation is coupled with the fluid flow simulation to obtain robust results.

Various processes in different industries can be calculated and optimised using this method.

For example, metallurgy, food technology, pharmaceuticals, architecture engineering, power plant technology, etc.

FAQ

Common questions

Can large geometries and mass flows also be calculated?

The program-architecture allows the use of parallel GPU processors, so that large numbers of particles or mass flows can also be calculated.

Can heat transfer and mass transfer be integrated into the models?

Yes, in addition to the heat and mass transfer models, there are also models for the fracture modelling of particles. In addition, wet and adhesive particle flows can also be modelled.

How accurate are the results of the calculations and how valuable are they?

As we usually perform smaller validation calculations in our laboratory, the exact parameters for an accurate simulation can be implemented. In addition to shorter commissioning times, the results also save significantly fewer development cycles and accurately designed lasting durability in abrasive media.
