+GMRES is used to solve propagation (\telkey{SOLVER FOR PROPAGATION} = 7)
+and conjugate gradient + preconditioning = 34 for Poisson Pressure
+Equation (\telkey{SOLVER FOR PPE} = 1 + \telkey{PRECONDITIONING FOR PPE} = 34).
+With these choices, the accuracies for propagation and PPE can be let to default
+values (= 10$^{-8}$).
+These choices are more efficient than previous choices for this example:
+\telkey{SOLVER FOR PROPAGATION} = 2 (conjugate residual) and
+\telkey{SOLVER FOR PPE} = 7 (GMRES = default).
