The Initial Values node adds the initial values for the Electric field and Magnetic field variables that serve as an initial condition for the transient simulation.

If there is more than one type of domain, each with different initial values defined, it might be necessary to remove these domains from the selection. These are then defined in an additional Initial Values node.

Enter values or expressions for the initial values of the components of the Electric field E (SI unit: V/m) and Magnetic field H (SI unit: A/m). The default values are 0 for all vector components.
