The following parameter files are examples for the different 
flow solver configurations as explained in my CFD book:

cp2d.dat_LMPSC_stat_l2 behaves like "old" cc2d
cp2d.dat_LMPSC_stat_L2 simlar but with L2 control (see my book!)
cp2d.dat_GMPSC_stat uses projection schemes as solver instead of Vanka 
(as in cp2d.dat_LMPSC_stat), but reaches the SAME solution

cp2d.dat_GMPSC_vanKan behaves like "old" pp2d, but with L2 control

cp2d.dat_GMPSC_nonstat is the fully coupled Galerkin solver with 
the projection-type solver for the Oseen equations, but 
imbedded into the full multigrid framework

cp2d.dat_LMPSC_nonstat similar but with Vanka as smoother
