Time discretization

For the discretization of the time derivatives different schemes can be used. An explicit first order Euler scheme, a second order explicit Adams-Bashforth and a second order explicit Runge-Kutta scheme can be employed for all time derivatives, for the time discretization in equations ([*]) and ([*]) in addition a Runge-Kutta-Method of third order is available. By default the first order Euler-scheme is used, for information about how to apply another method, please refer to section [*].
