Chapter 5 introduces the reader into modern ODE solvers for transient problems solved by the Method of lines. Emphasis is on higher-order one-step methods which are most suitable for the combination with the spatially-adaptive finite element methods. Discussed are the explicit and implicit Euler methods, the concept of stiffness, the explicit higher-order Runge-Kutta methods, embedded Runge-Kutta methods and adaptivity, and general implicit Runge-Kutta methods. Emphasis is given to an introduction to stability of the ODE schemes. Introduced are the notions of the stability function and stability domain, and A- and L-stability. These concepts are applied to the previously-introduced higher-order one-step schemes. We also discuss the collocation methods, and the construction of higher-order implicit (Gauss and Radau) Runge-Kutta methods via the higher-order quadrature rules. This chapter is closed with the discussion of efficient Newton-type iterations for the application in nonlinear ODE systems.
