Class
Foam::PackingModels::Explicit
Description
Explicit model for applying an inter-particle stress to the particles.
The inter-particle stress is calculated using current particle locations.
This force is then applied only to the particles that are moving towards
regions of close pack. The resulting velocity change is limited using an
abstracted correction velocity limiter.
