When creating a compartmentation model based on Constructive Permeabilities, the permeability of a region is space is based on the cumalative permeability of the compartments (Polyline Lists) which enclose that region. This window displays and allows modification of the permeability of the space enclosed within an individual comparment based on its position within the compartment hierachy. This hierarchy can be displayed using the Hierachy Editor Window. The window can be docked with the left, right and bottom sides of the application window.
When enabled, the permeability of decendant compartments in the hierachy is adjusted to maintain the same 'actual' value when the permeability of ancestor compartments further up is modified.
