25  Foam::PackingModels::Implicit
26 
27 Description
28  Implicit model for applying an inter-particle stress to the particles.
29 
30  The time evolution of particulate volume fraction is solved for implicitly
31  on the eulerian mesh. The computed flux is then applied to the lagrangian
32  field. The gravity force can optionally be applied to the particles as part
33  of this model, using the keyword "applyGravity".
