When I run scipy.solve_ivp with LSODA or scipy.odeint, I set an rtol and atol as well as min_step. The desired behavior is to try to reach the fixed atol/rtol, but only let the step size go so small for memory and computation purposes. If it does not reach the tolerance with h=hmin, the integration should continue, perhaps with a warning.
