Richards works conceptually with numPhases == 2 but only one velocity
should be computed. Therefore we need to overload the velocity output.

fix inital solution

A preprocessor variable ISOTHERMAL was set to 0 per default in main.cc
while for switching, the variable NONISOTHERMAL was evaluated.
To fix, set NONISOTHERMAL instead of ISOTHERMAL in main.cc.

The condition leads to a velocity profile that spreads in all directions
at the outlet of a channel.

Previously it was (incorrectly) assumed that pressure is index 0 in primary variables,
u is index 1 and v is index 2.
