RMS voltage in time-dependent study

Please login with a confirmed email address before reporting spam

Hello!

In my simulations I have two voltages with different frequencies applied to two separate electrodes. I am using an Electric Currents (ECs) module and Time Dependent study for this. I also want to add a PDE which will be coupled with ECs. The problem is that in the PDE I need to enter RMS voltage and I don't know how to do this in a time dependent study. Earlier I simulated the same problem, but as I had only one frequency applied to both electrodes, I used Frequency domain study and in my PDE I entered V/sqrt(2) to get RMS values of voltage calculated in Electric Currents. I have a nonlinear system, so I can't add solutions for two different frequencies.

Can you help me with this, please? Thanks!
