I updated the test and fixed the indentation. Should be ready. |

Since this was approved and it doesnt affect existing functionality I will merge. |

As discussed during the user meeting yesterday it would be nice to be able to use the adiabatic pressure instead of the full pressure to determine the yield stress in the visco plastic rheology. This drastically improves the solver convergence behavior at the cost of reducing the accuracy of the plastic deformation (e.g. shear bands do not form at the correct angle). It is still a nice option for models that do not need to resolve shear bands anyway and/or are run for testing purposes.
The test shows the functionality works correctly, but I still have to update the test results with reference results from the tester, so do not merge yet.
