The Mark Components command finds all voxels of a specified Material ID that are connected to each other and to the selected boundaries. The connected voxels are then reassigned to a new Material ID selected by you. Mark Components can be used, for example, to validate that the structure model has a through-pore in the flow direction.

The Material ID defines the material for which the connected component analysis should be done.

The found connected components are then assigned to the selected New Material ID.

The selections in the Neighborhood Mode follow the rules explained in detail on the Cleanse Structure page.

Mark Components Connected to defines how the selection made in the Connected Sides panel is interpreted. When set to All Chosen Sides, only those connected components that are touching all boundaries selected in the Connected Sides panel are marked. If Mark Components Connected to is set to Any Chosen Side, the connected components only need to touch one of the boundaries chosen in the Connected Sides panel to be marked.

The following example uses a model generated with the GadGeo module of GeoDict to show the effect of several combinations of Mark Components Connected to and Connected Sides.
