In the section below several typical configuration examples which be explained in detail.
Warm state selection
In a lot of systems, for example NWS systems, only the state selection is configured. The time zero will in this case be equal to the system time.
...
When the system time changes the selected state will also change so the relative time compared to time zero will stay the same.
Relative period panel
When the forecaster wants to run a workflow for a certain period of time then the relative period panel is a good option to use. The picture belows shows an example of the relative period panel.
...
When the system time is changed then the start time and end time will also change so that the relative period will stay the same for a topology node.
Cold state from current run
To set the state selection at a node to the cold state selection which was used in another run the option coldStateFromCurrentRun can be used.
...
If time zero changes the cold state selection should also change to keep the relative period the same.
Forecast length
To set the forecast length at a fixed length the option forecastLength can be used.
...
Below a screenshot of the same node after the sytem time was changed. The time zero is changed but the end time of the node is still fixed at the same time.
Time zero
By default the time zero of a node is equal to the system time and not editable.
It is possible to make the time zero editable and to set it to a fixed date/time.
The code snippet below shows a configuration example.
| Code Block |
|---|
<node id="ZWF_LHM_Z0_REF2017BP18" name="Files LHM zonder zout">
<workflowId>ZWF_LHM_Z0_REF2017BP18</workflowId>
<timeZero date="2004-01-01" time="00:00:00"/>
<localRun>false</localRun>
</node> |
To make the time zero editable and/or to shfit the time zero compared to the system time the option timeZeroShift can be used.
| Code Block |
|---|
<nodes id="WaterOrder HADT1" name="Water Order Apalachia">
<timeZeroShift unit="hour" multiplier="0"/>
<node id="WaterOrder_HADT1" name="Adjust Water Order">
<locationId>HADT1</locationId>
<workflowId>CalculateSpill_WaterOrder_HADT1</workflowId> |
If the shift is set to 0 then the time zero is editable but equal to the system time.

Configuration options which apply to all nodes
The topology.xml has two types of configuration options. The first group is applied to all nodes, the second group is applied to individual nodes. In this part the first group of options will be explained.
