Click to expand... If the simulation is driven modal, you can assign modal excitation strengths under HFSS->Fields->Edit Sources twinklee said: and how can we find which mode or modes are excited (in HFSS or CST)? with surface current?! Click to expand... Select a surface, plot the surface currents under HFSS->Fields->Plot Fields->J->Vector_Jsurf, and observe them for the various excitations.

Driven modal simulations excite certain modes (which you specify) into and out of a waveguide or transmission line.
