Defining Forced Excitation Values

You can replace the model parameters values to be used at a given time for some variables: input ports, Modelica parameters.

Note that defining or modifying these execution model values do not modify neither the model values nor the initial value.

Before you begin: Create a system experiment and define initial excitation values.

  1. Select a scenario from the MSR tree.

  2. Select New Forced Values from the Experiment Specifications toolbar.

    The Forced Values dialog box appears and displays the model structure from the function/logical component to the dynamic or state logic behavior.

  3. Expand the behavior and select an input or a variable.

  4. Modify or remove a value in the Forced Values column.

    Tip:

    The format of the value is a table with dimension 2xn with a Modelica format: [[t1, x1] [t2, x2]...[tn, xn]] or [[t1, x1];[t2, x2] ;... ;[tn, xn]].

    t is the time when the value x will be forced.

    t must be positive.

    If the t values are not ordered, the table will be automatically re-ordered.



  5. Click OK to close the dialog box and validate your modification.

    In the MSR tree, a Forced Values node appears in the Scenario category.

  6. If you need to edit a forced value, double-click its node from the tree.

    The Edit Forced Value dialog box appears to let you modify the forced values.
