Harmonize FreeFlow vtk output with PM vtk output
The compositional models produce inconsistent output:
PM 1pnc: x_compName
PM 2p2c: x_phaseName^compName
FF 1pnc: x^compName_phaseName
Shall we drop the name of the phase for the FF 1pnc model? Other models should be checked as well.
Furthermore, sometimes pressure
and sometimes just p
is used. We should also agree
on a common way for that.
This requires changing the names in the vtk reference solutions.
