In numerical analysis, the Runge–Kutta methods are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations. These methods were developed around 1900 by the German mathematicians Carl Runge and Wilhelm Kutta.

For nonlinear problems, in general, explicit methods are more efficient and implicit methods are more stable. For linear structural dynamic systems, the methods (Bathe, 1996; Butcher, 2016) for determining the numerical properties of a time integration … WitrynaTime integration methods. In circuit simulation, we generally deal with stiff problems, i.e., problems with time constants that may vary by multiple orders of magnitude. Implicit time integration methods are employed for this type of problem. In the following, their advantages and drawbacks are briefly discussed. fish eating game download
