Network Analysis and Composite Excitations

Network Analysis and Composite Excitations are used with driven modal, terminal, and transient problems. These options determine how HFSS applies excitations on a design during the adaptive refinement solution process.

When the Network Analysis option is selected, HFSS solves the design by exciting the ports individually and loading the remaining ports by matched characteristic impedances. Therefore, the number of solutions that HFSS calculates is equal to the number of ports on a design.

When the Composite Excitations option is selected, all the existing ports in a design are excited at the same time so HFSS needs to solve the design just once. The solution generated by Composite Excitations is much faster than Network Analysis.
