Solve the equation: k = f(x + dt k, t), for the unknown k at the current time t.
For general F and G, the equation for k becomes: F(x + dt k, k, t) = G(x + dt k, t).
The input vector x corresponds to time index (or cycle) n, while the currently set time, t, and the result vector k correspond to time index n+1. The time step dt corresponds to the time interval between cycles n and n+1.
This method allows for the abstract implementation of some time integration methods, including diagonal implicit Runge-Kutta (DIRK) methods and the backward Euler method in particular.
If not re-implemented, this method simply generates an error.
