DEM facilitates simulating tablet coating, mixing, packing and other applications in the Life Sciences Industry
Particles are found everywhere in the Life Sciences Industry and DEM leads to solids handling solutions, whether you need to analyze the chaotic movement of particles in fluidized beds, improve tablet coating uniformity, or find a cost-effective solution to equipment erosion.
  • Polyhedral mesh for pill coating application using STAR-CCM+
  • DEM simulates the motion of a large number of interacting particles and tracks them in a numerically efficient manner, modeling contact forces and energy transfer due to collision and heat transfer between particles. Shown is a DEM simulation for a fluidized bed.
  • Tablet coating in a rotating drum : STAR-CCM+ was used to improve inter-particle coating uniformity by using optimal spraying equipment settings

With recent advancements in numerical simulation technology, it is now possible to effectively simulate and understand the behavior of bulk material handling and granular flows.

In STAR-CCM+, the Discrete Element Method (DEM) is used to simulate particle flow for these applications.

DEM can be used to simulate the motion of a large number of interacting discrete particles, such as the granular flow of encountered in tablet coating, mixing and packaging. DEM tracks the interaction between every particle in a numerically efficient manner, modeling contact forces and energy transfer due to collision and conductive and radiative heat transfer between particles.

STAR-CCM+ is the first commercial engineering simulation tool to include a DEM capability that is fully coupled with numerical flow simulation in a single software environment.
