I'm currently trying to model, in COMSOL, a Doppler shift induced in a microwave signal by a flowing liquid in order to measure the flow speeds (Microwave flow meter).
I'm struggling with actually defining the doppler shift in the model. I know COMSOL have a doppler shift example but this is through their Acoustic package which involves different governing physics.

Any help appreciated.
