 N2 is injected in an aquifer previously saturated with water with an injection rate of  $`0.001~kg/m*s`$.
 The aquifer is situated 2700 m below see level and the domain size is 60 m x 40 m. It consists of two layers, a moderately permeable one ($`\Omega 1`$) and a lower permeable one ($`\Omega 2`$).

 ### 5. Setting up a new executable (for a non-isothermal simulation)

 ```bash
 cp exercise1_2p.cc exercise1_2pni.cc

 * In  `exercise1_2pni.cc`, include the header `injection2pniproblem.hh` instead of the isothermal problem file `injection2pproblem.hh`.

 * The following set-up should be realized:
 
   __Boundary conditions:__ Dirichlet conditions for the temperature with a temperature gradient of 0.03 K/m and a starting temperature of 283 K.
 
   __Initial conditions:__ The same temperature gradient as in the boundary conditions with an additional lens (with position: 20 < x < 30, 5 < y < 35), which has an initial temperature of 380 K.

 The non-isothermal model requires additional spatial parameters like the thermal conductivity. They are already implemented in `injection2pspatialparams.hh`, you just need to _uncomment_ them.
