Mark Components finds all voxels of a specified Material ID that are connected to  each other and to the selected boundaries. The voxels found to be connected are then reassigned to a new Material ID selected by the user. Mark Components can e.g. be used to validate that the structure model has a through-pore in flow direction. Click the Options’ Edit… button to open the Mark Connected Components dialog.

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

New Material ID assigns the material to be applied to the connected voxels.

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

Mark Components Connected to defines how the connected sides are 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.
