I have applied a pressure field on a blade with a certain frequency range to observe its response in ANSYS using modal superposition method and got my result. Now I want to apply another pressure field on the blade with twice the frequency to simulate the EO excitation in aeroengine.

I wonder if modal superposition method supports applying two excitations with different frequency, if yes how can I do it and if no what method can I use to simulate the EO excitation with two frequencies which one is twice the another.
