Viewing Results in the GeoPlan

Results can be illustrated in the GeoPlan, which gives you the opportunity to replay a run and see how the network changes over the period of the simulation. Using the thematic options, you can monitor the effect of the run on a number of network parameters.

Results can be viewed as follows:

1. Open the example network, if it is not already displayed, in the main window:
1. Drag the 'Obs4p' simulation object icon (not the rainfall event of the same name) from the Run Group in the Explorer window onto the main window. The network is opened in the GeoPlan.
2. Increase the size of the GeoPlan window and use the (Zoom in) and  (Pan) buttons to zoom in on the part of the network leading to the outfall in the north-east corner of the network.

2. Add arrows to the links to indicate the volume of flow.
1. Right-click the network and select Properties & Themes... from the pop-up menu, and the GeoPlan Properties and Themes dialog is displayed, opened on the Layers and Themes tab.
2. In the Conduit row, click Edit in the Theme column.

   The Conduit: Base Theme window is displayed.

3. Create a new sub-theme:
   1. Click (the Add button) in the Sub Theme Manager Pane.
   2. Type-in a name for the new sub-theme, such as 'Downstream Flow', in the Name field.
4. Select an option from the Field drop-down list. Make sure you use a SIM field such as sim.ds_flow (DSflow).
5. Ensure that the check box for the Arrows and Arrow Style options in the Properties pane are checked.
6. In the Ranged Themes pane, select the number of arrows that are to appear on the line (conduit) from the Arrows drop-down list.
7. Select the style of arrows from the Arrow Style drop-down list.

8. Click the OK buttons to close the dialogs.

   The arrows are now displayed on the conduits in the GeoPlan.

3. Click the (Play) button in the Replay Control toolbar to play the simulation. The direction of flow in the pipes is illustrated by the number of arrows on the links. You should be able to see how the flow through the pipes connected to the pumping stations changes as the pumps are switched on and off. The current date and time of the simulation are shown in the top left corner of the GeoPlan window. If you want to play the simulation again, you must first click the (Rewind) button. The other buttons on the toolbar let you control the way the simulation is replayed. For example, you can pause the simulation, move forward or backwards one timestep at a time, or jump to the end of the simulation.
4. You can display a graph of the effect of the simulation on various parameters for any point in the network. For example, you can view a graph of the flow through a particular link:
• Click the (Graph) button and then on a link. A dialog is displayed, listing the parameters that are available.

  Show meYou can select more than one parameter by holding down CTRL as you click the parameters. Deselect a parameter by clicking it again.

  

• Select a parameter from the dialog and click OK. The graph view is displayed and the window can be resized.

  Show me

  

  The vertical red line shows the current time in the simulation.
5. Close the graph window when you have finished viewing the results. Click the button in the top right-hand corner of the window
6. Hold down the CTRL key while clicking a network object with the (Graph) button to display a grid of results for a particular link or node. Alternatively, you can use the (Grid) tool and click the link.

7. Close the grid window when you have finished viewing the results. Click the button in the top right-hand corner of the window
8. Use the (Properties) tool to display the properties for a link or node.

   Show me

   

9. Show the results for the selected object at the current timestep. Use the (Jump to/replay options) button to display the Replay Options dialog, which you can use to advance the simulation to a particular time.

   Show me

   

10. Use the slider to jump to the required time and then click OK before clicking the object.
11. Click Cancel after viewing the results.
12. View the time-varying results on a grid as the simulation progresses:
1. Click the button to rewind the simulation back to the start.
2. Select the Grid windows | New link results window option from the Window menu.
3. Click the (Play) button. The values of the parameters change as the simulation progresses.

   Show me

   

4. Close the grid after viewing the results. You can also watch the parameter values for other types of network objects (using one of the 'results' options from the Window | Grid windows menu.
13. You can use themes to illustrate the change in a number of parameters as the simulation progresses. For example, you can show the change in volume in each link:
1. Right-click the network and select Properties & Themes... from the pop-up menu, and the GeoPlan Properties and Themes dialog is displayed, opened on the Layers and Themes tab.
2. Ensure that the theme, selected in Step 2 c, is highlighted in the left pane.
3. From the Field drop-down list, select sim.ds_vel (DS Velocity).
4. Ensure that the Use AutoRange check box is selected.
5. Check the Line Colour and Line Width options in the Properties pane.
6. Use the + or - buttons to ensure that the Value count is set to 5 for the number of Ranged Themes.
7. Choose a Line Colour for the first and last Values in the table, and then click the line colour Auto-Theme button.
8. Select a Line Width for the first and last Values in the table, and then click the line width Auto-Theme button.

9. Click Apply.
10. Check how your theme looks on the GeoPlan.

11. If you are unhappy with any of your theme selections, then change them as required. When you are satisfied with the display:
12. Turn off the display of the arrows on the links by removing the check in the Arrows box in the Properties pane.
13. Click OK on both windows.
14. Click the button to rewind the simulation and then on the button to play the simulation again.

    Show me

    

    The thickness of the lines and their colours illustrates the downstream velocity in each conduit over a period of time. You can set up the other themes to show what happens at each node or subcatchment.
15. You can, if you want, save the theme by right-clicking 'Theme Group' in the Explorer window tree view for the 'Langley Catchment Study' model group window and selecting New InfoWorks | Theme option from the pop-up menu.
16. Enter 'Link - ds_vel' in the New Name dialog and click OK.
17. If you want to, turn the theme off by clicking the Link theme in the Thematic Key window and pressing DELETE on the keyboard.
14. Add labels to show the values for specific links:
1. Right-click the network and select Properties & Themes... from the pop-up menu, and the GeoPlan Properties and Themes dialog is displayed, opened on the Layers and Themes tab.
2. Click the Edit button on the Custom Label column for the Conduits.

   Show me

   

   The Custom Labels Settings dialog is displayed.

3. In the Content tab, select the Field List option on the left and check the ds_vel (DS Velocity) box.

   Show me

   

4. Click OK.
5. Click OK again to close the GeoPlan Properties and Themes dialog.
6. Select the (Label) tool.
7. Click a link to show (or hide) the label for that link.
8. Drag the label to move it to a new position.
9. Label other links in the same way.
10. Replay the simulation. The labels will show the velocity in the conduit during the course of the simulation.

    Show me

    

    You can show several values in each label box by selecting other fields in the Network Label Field Settings dialog. You can also add labels for other types of link and for nodes.
11. You can save the theme as described in Step 13 o - q.
