CFD-DEM modelling of fibres in mold flow

Combining coupled CFD-DEM numerical techniques with multi-sphere DEM particle allows the simulation fibres for instance in polymer mold flow.

Combining coupled CFD-DEM numerical techniques with multi-sphere DEM particle allows the simulation fibres for instance in polymer mold flow. This simulation handles long fibres (currently rigid) as multi-sphere particles. Due to local drag force calculation the fibres interact with flow gradients.
