Explicit Runge-Kutta of a Differential Equation

HakikiCanakkaleli · September 22, 2014, 10:01

Hi,

== 1 ==
I would like to solve a differential equation with explicit Runge-Kutta method.

== 2 ==
The equation, in which

will be found, is:

$\frac{\partial k}{\partial t} + \frac{\partial k}{\partial x} = - A k + B$

== 3 ==
Is it possible to show me the main steps of the application of the Runge-Kutta method to this differential equation?

Many thanks in advance for any help.

if you search for rhocentralFoam runge kutta you ll find a solver rhoCentralFoamRK4

It is an example of an explicit Runge Kutta solver.
