I am calculating two PDEs, containing two variables (using a vector aproach, as described in https://www.dealii.org/8.5.0/doxygen/deal.II/group__vector__valued.html). Thus both variables (or their solution) are stored in the solution-vector. Is there a way to separate them, so that I can get the maximum value of each variable? If I call vector.max(), I get the maximum value of both variables combined.
