Click through our range of case studies below to find out how Aspherix® and CFDEM®coupling is applied to effectively support simulations in various industries.
Twin-screw extruders (TSEs) are widely used for processing polymers, chemicals and foodstuff.
Development of a 1D-3D model for polymer extrusion in TSE (collaboration with Novartis*)
The 3D part consists of DEM simulations of representative volume elements (RVEs)
The 1D part is a low-order model bridging the solution between the RVEs

The goal of this case study with Aspherix® and CFDEM®coupling was the optimization of a mower deck with respect to ths cut quality. Since the design contains blades with intersection trajectories it was not possible to use sliding meshes. An immersed boundary approach, especially designed for mower deck applications was used. The simulation results matched experimental data and it was possible to compare different geometry setups and boundary conditions and optimize them.
