Defining Execution Parameters Initial Conditions

You can modify the model parameters values that will be used during a virtual execution.

Note that modifying these execution values do not modify the functional / logical model values.

Before you begin:
  • From the Package Browser, open the Modelica Standard Library, then select Mechanics > Multibody > Example > Elementary to activate DoublePendulum.
  • From the Component Browser or from the diagram, select boxBody2.

    The Parameter and Variable Editor displays the boxBody2 model parameters values.

    For the purpose of this scenario, you will define a new width value for the virtual execution.
