Note that if provided tolerance requires a time step lower than provided minimum stepsize then an exception will be thrown by default. Every adaptive stepsize integrator provides constructors to circumvent this behavior: in that case, if a lower time step than minimum stepsize is required then minimum stepsize is used (hence tolerance is not respected for this step). This is particularly useful for some particular dynamics such as reentry.
