You can control the behaviour of a running model by changing parameter values on-line:
1.In the tree-view click the Variables node.
2.Click on the plus sign to show all the underlying submodels.
3.Select the desired submodel.
4.Select the desired parameter.
5.In the Value field at the bottom of the tab, change the parameter value, followed by the Enter key.
The changed value will now become blue to indicate that the value has been changed locally but not yet applied on the running model. The value has not been applied instantly since you may desire to change multiple values at the same time.
6.If desired, repeat the previous steps to change other parameter values.
7.Click on the Apply button at the bottom of the tab, to apply the changes.
The color of the changed parameters returns to black again when their new values are applied.
You can change multiple parameters values and click Apply to instantly apply the changes.
