I am new to comsol and cannot figure out how to assign a rect function as the input source to a strip of copper. I subsequently need to study the thermodynamics (which I have successfully done in steady state)

Thanks

Hi

if you are in time dependent case, write V=V0[V]*rect1(t[1/s]) for a ptential defines as per your rectngle function you can make in Model - Define - Functions

Good luck
