(1)-(7).
Takes the same inputs as :func:conv_observed_order (three solutions, finest first, and
the refinement) and returns, with p from eq. (3):
phi_ext21 = (r21^p phi1 - phi2) / (r21^p - 1) (4) (and phi_ext32)
e_a21 = |(phi1 - phi2) / phi1| (5)
e_ext21 = |(phi_ext12 - phi1) / phi_ext12| (6)
GCI_fine21 = 1.25 e_a21 / (r21^p - 1) (7)
(safety_factor = 1.25 as in eq. (7)). Fractions and percentages are both returned, and
report reads “phi1 +- GCI”. Note what the GCI is not: it bounds the discretization
error of the fine solution only — “this does not account for modeling errors” (Celik).
Refusal as in :func:conv_observed_order, plus phi1 = 0 or phi_ext = 0 (relative errors
undefined). Defaults: Celik Table 1, first column (GCI 2.2 %).
