Analysis Setup in Time Domain

Two classes of analyses exist: those focused on device characterization, and more general analyses. In the case of device characterization, one is interested in quantities like S-parameters and/or time-domain output at ports due to excitation of a specific port. This requires that excitations be "on" one at a time. For each active port and mode, a separate simulation is done. These simulations are independent and can be distributed over a network, to be executed in parallel. Each active port and mode will employ an excitation with the same time profile.

In the more general analysis type, all active ports and modes are "on" simultaneously. Each one can have an excitation with a different time profile. This type of analysis gives you more freedom, but S-parameters cannot be extracted.

In both classes of simulations, fields can be saved and visualized.
