Minimum Size

Group (Subgroup)

Processing (Cleanup)


This Filter removes Features that have a total number of Cells below the minimum threshold defined by the user. Entering a number larger than the largest Feature generates an error (since all Features would be removed). Hence, a choice of threshold should be carefully be chosen if it is not known how many Cells are in the largest Features. After removing all the small Features, the remaining Features are isotropically coarsened to fill the gaps left by the small 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.


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.


Name Type Description
Minimum Allowed Feature Size int32_t Number of Cells that must be present in the Feature for it to remain in the sample
Apply to Single Phase Only bool Tells the Filter 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
