| CompositStructures | The Composite structures is a list of all unique positions in the network with a structure. Each composite structure can contain more than one structure, also called parallel structures. This list of composit structures is a computational list, created during Initialize(). |
| Parameters | Parameters used during initialization |
| RemovableStructureLocations | List of locations of structures that can be removed, and replaced by an ordinary HD calculation, as if there where not structure there originally. |
| Structures | The list of all structures defined. |
