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.

This stage assumes that you have started InfoWorks WS Pro and that the Model Group window is open, showing the Newtown icon.

The tutorial dataset uses InfoWorks WS Pro native units (metric units). To import the tutorial data correctly, set the user units to metric by selecting Options from the Tools menu and clicking the Metric (Native) button on the Units tab.

Viewing results

  1. Let us open the example network if not already in the current window:
  2. You can add arrows to the links to indicate the direction and strength of flow.
  3. Click the Play (Play) button on the Replay toolbar to replay the simulation. The level and 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 (Rewind) button. ClosedThe other buttons on the toolbar let you control the way in which 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:
  5. You can hold down the Ctrl  key while clicking a network object with the Graph (Graph) button to display a grid of results for a particular link or node. Close the grid when you have finished viewing the results.

  6. You can use the Properties (Properties) tool to display the properties for a link or node.
    • Advance the simulation to a particular time before clicking the object.
    • Use the Show Results Show results icon on the toolbar to show the results for the selected object at the current timestep.

  7. It is possible to view the time-varying data on a grid as the simulation progresses:

Using themes to illustrate the change in parameters as the simulation progresses

Show the change in flow in each link

  1. Create a sub theme for the Pipe object layer and name it Flow Change.
  2. From the Field drop-down list, select 'sim.flow (Flow)'. This parameter is available only if there is a simulation.
  3. Check that the Absolute Values check box is turned on.
  4. In the Properties list, make sure Line Colour and Line Width are selected.
  5. In the Ranged Themes area:
    • Increase the value count to 5.
    • For the fifth value, select a line width of 5.
    • In the Line Width column, click Auto-Theme.
  6. If the Flow Rate sub theme created earlier is in use on the GeoPlan, disable it by selecting it in the left pane of the layer theme editor and clicking the Enable disable (Enable/Disable) icon on the toolbar.
  7. Click Apply to see the effect on the GeoPlan.
  8. Click OK to close the editor, then click OK to close the dialog.
  9. In the Replay toolbar, click the Rewind (Rewind) button to rewind the simulation and then Play (Play) to play the simulation again. The thickness of the lines and their colours illustrates the flow in each link over the period of the simulation. ClosedYou can set up the other themes to show what happens at each node .

    Flow Theme

Set up a theme to display the pressure at the nodes

  1. Create a sub theme for the Node object layer and name it Node Pressure.
  2. Choose the field 'sim.pressure (Pressure)'. This parameter is available only if there are simulations.
  3. In the Properties list, make sure Colour is selected.
  4. In the Ranged Themes area:
    • Increase the value count to 4.
    • Enter Values of <, 15 m, 45 m and 60 m. (Applying crosses to the boxes in the Fix column lets you make changes to the values.)
    • If you want to, change the default line colour scheme to, for example, red, green, yellow, and orange, by selecting those individual colours from the drop-down tool in the Line Colour column.
  5. Click Apply to see the affect on the GeoPlan.
  6. Replay the simulation to see the pressure change across the network.

    Pressure Theme

Set up a theme to show pressure contours across the network

  1. Create a sub theme for the Contour object layer and name it Pressure Contours.
  2. Choose the field 'sim.pressure (Pressure)'. This parameter is available only if there are simulations.
  3. Increase the value count to 11, enter 100 m for the last value, then click AutoScale.
  4. Click OK to close the editor, then click OK to close the dialog.

  5. Replay the simulation.

Add labels to show the values for specific links

  1. Load or create the Flow Change sub theme described previously.
  2. On the Layers And Themes page of the GeoPlan Properties And Themes dialog, in the Pipe object layer row, click the Edit button in the Custom Label column.

    Custom Label Edit button for Pipe object layer

  3. On the Content page of the Custom Label Settings: Pipe dialog, tick 'flow (Flow)', then click OK.
  4. Select the Label (Label) tool.
  5. Click a link to show (or hide) the label for that link.
  6. Drag the label to move it to a new position.
  7. Add labels to additional pipes and move them so that you can see them clearly.
  8. Replay the simulation. The labels will show the flow through the pipes during the course of the simulation. ClosedYou can show several values in each label box by selecting other fields in the Custom Label Settings dialog. You can also add labels for other types of link and for nodes.
