I'm using the Comsol 5.5 to simulate the distribution of potential V along the length of the line (transmission line). Frequency domain analysis.
I use 2 study - the first 10 Hz, 1 volt on the incoming Lumped Port. The second is 1000 Hz, 1 volt on the incoming Lumped Port.
How do I summarize up these two potential distributions to get a complex wave graph? Example: 1000*V(from study 1)+10*V(from study 2) (like non-sinusoidal waveform from VFD)
