+The picture shows the adaptive refinement and as well how much a cell is
+plastified druing the contact with the ball. In the middle - where the
+mesh is finest - you can see the hollow caused by the ball. The blue
+color means that this cell contains only elastic quadrature points in
+contrast to the red cells in which all quadrature points are plastified.
+Since we used trilinear ansatz functions each cell contains eight
+of these points which may or may not be elastic or plastic.
