Hi

I need to calculate the Root mean square (RMS) of a voltage. Are there any predefined functions in Comsol to do so. I searched the docs and got no clue on that.

Thanks a lot

Hi

not directly, but if you are doing a frequency domain sweep, you get amplitudes out the RMS are sqrt(2) apart, provided you have any phase info under control

For certain table operation in the derived Variable section, you can apply "Data Series operations" columnise, there you have an RMS operator

Good luck
