| 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. | |
