The code is also quite long and messy compared with codes using Runge-Kutta time dis- cretizations. We present a novel mapping approach for WENO schemes through the use of an approximate constant mapping function which is constructed by employing an approximation of the classic signum function. EulerWeno5 These are two (very basic) implementations of the 5th order WENO scheme for the Euler Equations with two components, using Lax-Friedrichs flux splitting. It exemplifies the implementation of the component-wise reconstruction for finite-difference (FD) and finite-volume (FV) methods. The main drawback of the WENO-5 scheme is that we have to increase the stencil size to get more accuracy. Now, it seems that this method is used when operating on cell centre values. .
