I’m trying to simulate a silicon heater and especially look at the current with respect to increase in voltage. I have included both charge and heat solver in my simulation. When I simulate both the solvers separately, I get a different IV curve for both. For instance, I get a current of ~22mA at 2V for my charge solver, and for the same voltage, I get a current of ~0.4mA for my heat solver.
Can you please help me understand why there is a difference in IV curves for the same design specs.
