connectivity assessment

This module allows you to assign data and subset all (or selected) discrete (disconnected) regions of plumes or lithologic materials.

 

• OVERVIEW: When we create subsets of models, either based upon analytical data, stratigraphic or lithologic modeling these subsets often exist as several disjoint pieces.

  • In the case of analytical (e.g., contaminant) plumes, the number and size of regions (pieces) can strongly depend on the subsetting level.

  • With lithologic models, the number and size of the regions depends on the complexity of the lithologic data and the modeling parameters.

• FUNCTION: The connectivity assessment module assigns a new data component to these dis-connected regions.

  • The pieces are sorted based upon the number of cells in each piece.

    • This is generally well correlated to the volume of that regions, but it is definitely possible that the region with the most cells may not have the greatest volume.

  • The highest cell count region is assigned to 0 (zero) and regions with descending cell counts are assigned higher integer values.

• PARAMETERS:

  1. Merge Cell Sets (toggle): Merges cell sets such as stratigraphic layers or lithologic materials. Generally should be on when dealing with analytical data.

  2. Assessment Mode: Determines the criteria for subsetting of regions and/or assigning data

     1. Add Region ID Data: Does not subset, but assigns Cell Data corresponding to cell counts

     2. Subset By Region ID(s)

     3. Region Closest to Point

     4. Region with most cells: Outputs Region ID = 0 without assigning data.

  3. Point Coordinate: Is the X, Y, Z coordinate to be used for "Closest region"

  4. Region IDs: The list of regions to include in the output if Selection Mode is set to "Subset By Region ID"
