Then, it is interesting to compare actually computed values of the quantity of interest (i.e. the x-derivative of the solution at one -point) with a reference value of -0.211289... plus or minus -0.000002. We get this reference value by computing on finer grid after +point) with a reference value of -0.0528223... plus or minus +0.0000005. We get this reference value by computing on finer grid after some more mesh refinements, with approximately 130,000 cells. Recall that if the error is O(1/N) in the optimal case, then taking a mesh with ten times more cells gives us one additional digit
