SplitFieldByConnectedRegion

This module splits a domain into separate fields as defined by the input field’s connectivity.

Detailed Description

This module divides a single input field into as many as 8 output regions. Separate regions may also be collected and bundled. Connected regions are not defined by label masks. They are defined, rather, by node and/or element connectivity. For example, a continuous, tetrahedral mesh may use label masks to define domains, but this module will produce only one output field given that all tets within the mesh are connected.

A common use for this module, then, is to separate distinct field surfaces, to split away small mesh islands that are not connected to the main mesh, or to break up a fractionated mesh into its individual regions.

Domains can be sorted in two ways: Sort Domains by Size or Sort Ascending. Domain size refers to the overall surface area (if domains are surfaces) or volume (if domains are 3-dimensional). The ascending sort refers to the value assigned to each domain in the original field.
