WhatIf Editor: only activated for IFD segment nodes associated with a whatifTemplate

If the segment node does not allow a whatif to be created, all options in the whatif-editor are disabled.

WhatIf Editor: Create button

If the segment node allows the creation of a whatif-instance, the name and description field are enabled. When the user has filled in the name, the Create button is enabled. After pressing the Create button, the what-if instance is created and added with a specific WhatIf icon (white background and a bleu hammer/wrench) under the segment node. The cursor automatically selects this what-if node in the IFD-tree.

Once created, the button row changes. the new buttons are Copy, Save, Delete, Import and Export.

their behaviour is explain on this page.

Once created, a Delete button is activated to allow deletion of the whatif. Note that non-persistent whatifs remain in the database, also after the application is exited. As long as they are not run serverside, they will only be available to the user who created this what-if.

WhatIf Editor: Create buttonWhatIf Editor: Specifying the what-if content : properties

After pressing the Create button, a whatif-instance can be populated via the controls in the whatif-editor tablethe what-if editor shows a table with the property-fields and/or modifiers to be specified. Within the WhatIfTemplate configuration, the data entry table may have been organized in subsections, separated by bold row indicators.

Integer, double and string properties can be entered in the text field. Min/max ranges may apply to the numeric values. Booleans properties can be manipulated via a checkbox. Properties with enumerated values, properties referencing configuration files or properties referencing config files associated whatif-instances can be selected via a dropdown box.

A whatif-template can also reference modifierTypes. For each configured modifierType, a dropdown will be shown listing the names of the modifiers available for selectionWhen pressing Save, the specified property settings are saved to the database.

WhatIf Editor: Apply buttonSpecifying the what-if content : editing embedded modifiers

A whatif may also hold modifiers which are specifically associated with this whatif.

Timeseries modifies, typical profile modifiers and location attribute modifiers can be created inside the whatif editor by pressing the wrench icon inside the table. This unfolds a panel with editing options.

As soon as the Apply button of the modifier is pressed, the modifier content and the modifier-whatif association is saved to the database.

WhatIf Editor: Save button

The Save button is available to save

After pressing the Apply button, the new whatif-instance is created and added with a specific WhatIf-icon (hammer and wrench) under the segment node.

As you can see, when this whatif-node is selected in the tree, the Create button has changed in a Copy button.

The Apply button is available to apply any adjustments made to the whatif-instance. Adjustments can be done as long as the whatif-instance has not been saved persistently to the database by execution at the server or (after a local run) pressing the Save button Disk icon in the IFD to promote the local run to the database.Once specified, a Delete button is activated to allow deletion of the whatif. Note that non-persistent whatifs remain in the database, also after the application is exited.persistent server run.

WhatIf Editor: Copy button

When a whatif-node has been selected in the IFD-tree, the Create button has changed into a Copy button.

When pressing the Copy button, the settings of the selected whatif-instance are copied to a new instance. Both the old and new instance appear next to each other, where the new instance can be adjusted.

After pressing Apply a child node is added to the whatif-node you copied from.

Note: the parent-child organization is only visual and decided at creation time. Only at creation time, once can assume that the whatif-settings are the same. No facilities exist for moving child nodes from one parent to another parent or any other way of reorganizng the whatif-nodes in the tree

Running (IFD)

Running a whatif is conducted via the normal run facilities in the IFD-tree. By pressing the Run button in the IFD-task tree, the workflow associated with the (parent) segment node is executed using the whatif-settings.

The icon status of the segment node will reflect the status of the last run. The icon status of the whatif-node will reflect the status of the whatif-run.

Whatif icons can have various backgrounds/foregrounds (hammer & wrench):

• white/blue: whatif specified, not executed (can still be adjusted)
• blue/white: whatif locally executed (can still be adjusted)
• green/white: whatif executed and persistently save in database (cannot be adjsuted anymore)
• red: whatif run failed
• yellow/blue: whatif has been adjusted after local execution

Note: a when the T0 of the run has changed compared to previous runs, segment nodes will chnage accoring to their normal status update. A segment node with a black icon background indicates that the last run executed at another T0 has failed. A segment node with a grey background indicates that the last run executed at another T0 was succesful. The color of the check indicates whether this run was local (blue), persistent (green) or the settings have changed (yellow).

WhatIf Editor: Delete button

WhatIf-instances can be deleted using the Delete button in the WhatIf Editor. When deleting a whatif a popup appears with three choices:

• delete entire what-if (=delete whatif-instance holding the specification, delete associated whatif-results)
• preserve what-if definition (=delete whatif results, while preserving the whatif-instance holding the specification)
• preserve modifiers associated with whatif (=delete whatif results, delete whatif-instance holding the specification, preserve any modifiers included) 

WhatIf Editor: compare inputs

WhatIfs can be compared by selecting multiple whatif-nodes having the same underlying whatif-template (typically two nodes within the same segment node).

When looking at the WhatIf Editor, the whatif-specifications will be placed next to each other in the table view.

Showing WhatIf results:

Whatif results can be accessed by selecting the whatif-node in the IFD-Task tree and navigating to the TimeSeriesDisplay or the Spatial Display.

The Time Series Display always will show the latest Local or Current run (whatif or not). The selected whatif may be added to this view.

The Spatial Display always shows the results of the selected WhatIf if the gridplot to be visualized is generated by the workflow associated with the whatif. If the grudplot is generated  by another workflow, the Current run of that workflow is shown.

WhatIf: compare outputs (TimeseriesDisplay)

When looking at the Time Series Display , the latest Local or Current run of this workflow (whatif or not) will be shown as well as the selected whatif runs (i.e. the previous current ones).

When the statistical function 'differences' is available, once can choose a 'base run' to compare the other runs against. Differences between runs can be shown either in absolute or relative terms.

WhatIf: compare output (Spatial Display)

WhatIf results can be compared spatially by selecting two whatif-nodes (within the same segment node).
