 NERD scheme (\# 13) can also be used for that purpose.
 The GMRES is used for solving the propagation (option 7 = default choice)
 whereas the conjugate gradient (option 1) combined with preconditioning = 34

+= 2 $\times$ 17 is used for solving PPE as more efficient than GMRES for this
 example.
 Moreover, preconditioning for velocities is also set to 34 (a little bit
 more efficient).
