Harvester 4-way Coupled - IB Geometry Detail

Using fully coupled Aspherix®-DEM and CFDEM®coupling simulation we are able to model arbitrary motion of geometry parts using „Immersed Boundary“ technique as it is applied here for the "wiggle" motion of the chaffer inside a combine harvester. Straw and wheat is inserted as a stream from the top and due to segregation and sieving these are separated. The shape and orientation of the particles determines their drag force.
