Hello! This is my first post. I'm a diligent university student, and am not very confident when I create my own circuits. I searched for an analyzer for a while, and found this website and was blown away. The design and UI are amazing; simple and quite robust. That said, I am having difficulty modeling a circuit the way I need to. I would like to define a voltage drop across a pair of nodes as a function of time, as in Vab=f(t), and then perform a time domain sweep. I would also like to define a current at an initial time. Is this possible at this time? Thanks all, Mitch

@mtrogers,

Welcome to CL.
