This modifier decomposes a particle system into clusters by grouping particles into disconnected sets. Each particle is assigned a cluster ID by this modifier.
A cluster is defined as a set of particles, each of which is within the cutoff distance from one or more other particles in the cluster. If a particle has no neighbors within the cutoff distance, then it forms a 1-particle cluster.
The modifier writes its results to the Cluster
particle property, which stores the
cluster ID assigned to each particle. Clusters have identifiers 1 to N, where N
is the number of clusters found by the modifier.
The maximum distance between two particles up to which they are considered neighbors that belong to the same cluster.
