I'm trying to simulate a circuit that dims a 12V lamp over a 1.5hour time period. I use LTSpice as my simulator.
I need to do the simulation over about 7000 seconds. I set this with a max step size of 1s, but for some reason LTSpice thinks it needs a step size in the us range. It will take days to co that simulation and would be so large as to be unusable.
How do I get the simulator to pick a "better" min step size?
The circuit I'm working from is here:

Also open to other ideas on how to do this.
thanks,
dave
