The DEM capability is fully coupled with a numerical flow simulation in a single integrated software environment. DEM simulates the motion of a large number of particles and tracks the interactions between them in a numerically efficient manner, modeling contact forces and energy transfer due to collisions and heat transfer between the particles.
DEM is an ideal solution for many biomedical device applications including studying particle deposition in human longs, modeling embolus in pulsatile flow or assessing accuracy of vascular filters for a specific particle shape.
In addition, using DEM leads to solids handling solutions for the pharmaceutical processing industry, whether one needs to analyze the chaotic movement of particles in fluidized beds, improve tablet quality and coating uniformity or find a cost-effective solution for equipment corrosion. The DEM capability in STAR-CCM+ can predict very dense particle flows in a reasonable time, making it practical for analyzing many real world pharmaceutical manufacturing processes such as filling, compressing, compacting, coating and drying.
