is model.set_initial_conditions_from() a good idea?

[Weisserlinks]

Dear all,

I'm now working on ageing experiments in Pybamm by cycling cells at different SOC. One of the tasks is setting the initial conditions for each cell. I've come up with 2 methods which are:

1. changing the initial concentration in both electrodes
2. doing pre-experiment, in which cells are discharged to different SOC, then using model.set_initial_conditions_from() so that the model inherits all last states from pre-experiments

The first way is essentially giving different input parameters and it should work. However, results showed that the 2. method is better. I'd very appreciate it if anyone can give more explanations about model.set_initial_conditions_from().

Best regards,
