Combine steady-state results.
XF's post-processing option allows users to make use of the electromagnetic principle of superposition in order to combine steady-state results from a single FDTD simulation that computed S-parameters for multiple ports. The superposition capability requires users to provide the set of port magnitude and phase values used to combine the results. See the antenna array use cases knowledge article for prerequisites and use cases.
Users can create a superposition simulation through the Simulations window by choosing Post Processing ❯ Superposition Simulation as the Create Simulation option in the upper-left corner, or through the Results browser by right-clicking on an existing superposition result and selecting Create New Superposition.
In the Create Superposition Simulation window that opens, the Name field at the top of the window provides space for a user-defined simulation identifier. This name appears in the Simulations window once the simulation is created, and is editable from that window through the right-click menu.
