Flow Network Map

thumb|Empty flow network map with default element target level and system element bar The flow network map provides a schematic overview of the river basin model. The system elements are represented by their symbols and the flow relationships between the system elements (system logic) by arrows.
When a variant is activated, the corresponding flow network map opens automatically. A empty variant contains an empty flow network map with the system outlet element as default.
Create new system elements
To create new system elements, drag and drop them from the system elements bar onto the system plan. The general system elements window automatically opens, where a unique identifier must be entered. All other settings and descriptions in this window can be filled in later.
The desired system element is selected...
...and dragged onto the system plan while holding down the left mouse button.
At the desired position you drop the element (Drag&Drop).
Finally, a unique identifier and a clear designation should be assigned.
Moving system elements
Existing system elements can be moved on the system plan by drag & drop.
Connecting system elements
To connect two system elements that have already been created, the start element is dragged onto the target element while holding down the control key. If an element is to receive several sequences, the process is performed several times. The first connection will automatically become sequence1, the second sequence2 and so on. If the sequence is to be changed, the connections must first be deleted and then reestablished in the desired sequence. Alternatively, right-clicking on the start element -> Sequences can also be used to assign the sequence elements and thus create a connection (see sequences tab).
Mark element with the left mouse button. Press and hold <CTRL> key.
Mark the element on the target element while holding down the <CTRL> key and the left mouse button
The flow relationship is set up.
Deleting connections between system elements
Analog to the procedure for creating new connections, existing connections can be deleted by dragging the start element to the target element while holding down the control key. Existing connections can also be deleted by right-clicking the start element -> Sequences (see sequences tab).
Selecting system elements
Use the mouse to mark the system elements within a rectangular area of the system plan. Right-clicking on a system element -> Select upper layer also allows to select all upper layers for this system element. Marking system elements can be useful for the automatic alignment of elements in the system plan (Menu View -> Align -> Top,...) or for list editing of elements (Menu System -> System Plan -> List Editing)
Moving the display area in the flow network overview
thumb|System plan section with overview. The red frame shows the currently displayed section and where it is located in the overall system plan. It can be moved by Drag&Drop. With very large system plans, it is possible that not the whole system plan fits on the screen and only a section is displayed. In the system plan overview in the lower left corner the whole system plan is displayed in small size and the current section is marked with a red frame. The displayed section can be moved by dragging and dropping the red frame in the system plan overview.
