 # This formulation is in a weak form type formulation and can be implemented by using the derivative
 # split matrix $D_{split}=(2D-M^{-1}B)$ and two different fluxes. We divide between the surface
-# flux $f=f_{sur}$ used for the numerical flux $f_{sur}^*$ and the already mentioned volume
+# flux $f=f_{surface}$ used for the numerical flux $f_{surface}^*$ and the already mentioned volume
 # flux $f_{vol}$ especially for this formulation.
