My coupled example crashes unexpectedly when the soil water potential is low, what should I do?

On some computers, the following change needs to be made in order to stop the coupled examples from crashing:

1. open the file "../DUMUX/dumux-rosi/cpp/soil_richards/richardsparams.hh "
2. delete line 77, phi_[i] = qs.at(i)... ; and exchange it with phi_[i] = 1;
3. go back to your DUMUX-folder and compile the model again: ./dune-common/bin/dunecontrol --opts=cmake.opts all
