Hi all
i want to put voltage source with two ampliude with two frequencies

v1= 13000*sin(omeg*t)
v2= 500 *sin (3*omeg*t)

i want to apply voltage = v1+v2 where omeg=2*pi*freq and freq=7000 hz

i want to get the responce after very long time so i want to solve by frequeny stationary solver

i don't know how to write applying voltage correctly in the model

help me please

Hi,

the frequency domain solver can only solve for one frequency. In your case I think you have two options:

1. Time dependent solver with your explicit function. This will take a lot of time to solve.

2. If your model is linear you can generate separate solutions for all frequencies you are intersted in and add the results.

Cheers

hi thank you for reply

i want to ask if i try to solve with frequency domain. is it possible?
