Design Properties

In this Eddy Current case, the moving bar is dependent on the coupling time provided by System Coupling. Review the design properties needed to support this.

  1. Select Maxwell 3D > Design Properties.

    The Properties: BarAndCoil – BarAndCoil dialog opens.

  2. In the Local Variables table, verify the following coupling-related design variables and their values:

    • Cur is the variable used to define the Current parameter. Note that its Evaluated Value is set to 1000 A.

    • SimTime is a user-created variable that maps System Coupling's time to Maxwell. It maps each coupling time step (in seconds) to Maxwell, which uses the information to move the bar and execute the analysis.

    • MoveX is set to the following expression:

      pwl(ds_Time_Pos,SimTime) /1000

      This is the displacement vector of the bar in the x direction. It is a function of the SimTime.
