Hai, I am fairly new to COMSOL. I have been trying to add a time dependent potential to my model. That is, I need the potential to be, say, 10V from 0 second to 5 second and then become 20V from 5s to 10s. Then solve it in time dependent solver for the total time. How to add such a time dependent potential in COMSOL? Any help on this matter is appreciated, thanks.
