Frequency Domain Perturbation Study Step
Usually, two different right-hand side contributions (or loads) must be defined for each step. The first step needs a stationary value for the contribution, and the second step needs the perturbed value for the contribution. The definition of these contributions differs between exclusive and contributing nodes, and this relates to the
Harmonic Perturbation
node, which can be added to a wide variety of physics interface nodes (for example, the
Electric Potential
and
Electric Ground
nodes for the
Electric Currents
interface).
