In order to complete this exercise you need a grid module capable of handeling
simplex grids, like \texttt{ALUSimplexGrid}. If this is not the case please skip this exercise.
Change the types of elements used for discretizing the domain. In line \ref{tutorial-coupled:set-gridcreator} of the problem
file the type of gridcreator is chosen. By choosing a different grid creator you can discretize the domain with different elements.
Hint: You can find gridcreators in \texttt{dumux/common/}, change for example from \texttt{cubegridcreator.hh} to \texttt{simplexgridcreator.hh}.

Besides adjusting the guardian macros, the new problem file should define and
use a new type tag for the problem as well as a new problem class
e.g. \mbox{\texttt{Ex2TutorialProblemCoupled}}. Similarly adjust your new spatial parameters file. If you are using Eclipse there is
e.g. \mbox{\texttt{Ex2TutorialProblemCoupled}}. The type tag definition has to be adjusted in \texttt{tutorial\_coupled.cc} too (see line \ref{tutorial-coupled:set-type-tag}).
Similarly adjust your new spatial parameters file. If you are using Eclipse there is
a very helpful function called \texttt{Refactor} which you can use to change
all similar variables or types in your current file in one go. Just place the cursor at the variable or type you want to change
and use the \texttt{Refactor} $\rightarrow$ \texttt{Rename} functionality. Make sure to assign your
