```c++
// define the type tag for this problem
-using TypeTag = TTAG(OnePCompressible);
+using TypeTag = Properties::TTag::OnePCompressible;
```
The TypeTag is created in the `1pproblem.hh`. There you can see that it inherits from the __OneP__ and additionally from the __CCTpfaModel__ which defines the discretization method, which is in this case the cell-centered tpfa method.
* a gridmanager tries to create the grid either from a grid file or the input file
```c++
-GridManager<typename GET_PROP_TYPE(TypeTag, Grid)> gridManager;
+GridManager<GetPropType<TypeTag, Properties::Grid>> gridManager;
gridManager.init();
```
* we create the finite volume grid geometry, the problem, solutionvector and the gridvariables and initialize them. Additionally we initialize the vtkoutput. Each model has a predefined model specific output with relevant parameters for that model.

// create the finite volume grid geometry
-using FVGridGeometry = typename GET_PROP_TYPE(TypeTag, FVGridGeometry);
+using FVGridGeometry = GetPropType<TypeTag, Properties::FVGridGeometry>;
