How to solve the solver problem like the minimun step size was reached?

[yif-xu]

Hi,

I added the custom termination simulation
`
soc_cutoff_termination = pb.step.CustomTermination(name='SoC cutoff', event_function=soc_cutoff)
terminations = [soc_cutoff_termination, '2.5 V']

experiment = pb.Experiment(
    [
        pb.step.c_rate(1, termination=terminations)
        
    ]
)`

It always gives me this error: - [ERROR] callbacks.on_experiment_error(235): Simulation error: FAILURE IDA_ERR_FAIL: Error test failures occurred too many times during one internal time step or minimum step size was reached.

I tried to change the rtol=1e-3, dt_min and max_error_test_failures, while I still got this error.
