Minimum Number of Neighbors¶
Group (Subgroup)¶
Processing (Cleanup)
Description¶
This Filter sets the minimum number of contiguous neighboring Features a Feature must have to remain in the structure. Entering zero results in nothing changing. Entering a number larger than the maximum number of neighbors of any Feature generates an error (since all Features would be removed). The user needs to proceed conservatively here when choosing the value for the minimum to avoid accidentally exceeding the maximum. After Features are removed for not having enough neighbors, the remaining Features are coarsened iteratively, one Cell per iteration, until the gaps left by the removed Features are filled. Effectively, this is an isotropic Feature growth in the regions around removed Features.
The Filter can be run in a mode where the minimum number of neighbors is applied to a single Ensemble. The user can select to apply the minimum to one specific Ensemble.
Notes¶
If any features are removed and the Cell Feature AttributeMatrix contains any NeighborList data arrays those arrays will be REMOVED because those lists are now invalid. Re-run the Find Neighbors filter to re-create the lists.
Parameters¶
| Name | Type | Description |

| Minimum Number Neighbors | int32_t | Number of neighbors a Feature must have to remain as a Feature |
| Apply to Single Phase | bool | Whether to apply minimum to single ensemble or all ensembles |
| Phase Index | int32_t | Which Ensemble to apply minimum to. Only needed if Apply to Single Phase Only is checked |
