This is a numerical study of ODE systems modelling the dynamics of a strongly damped stiff oscillator under periodic force. After reviewing the notion of stiffness, we demonstrate and discuss convergence order reduction for some well-established numerical integrators. We also include some comments on stiffness in nonlinear systems.
