[aspect-devel] VectorTools::integrate_difference fails to return an error that decreases under grid refinement (Harsha Lokavarapu)

[Harsha Lokavarapu]

With "set use year instead of second = true," the convergence results 
for the 2D spherical shell model using 
VectorTools::integrate_difference() are:

                                                     TABLE 03
      Refinement
         Level       |  L1 Velocity       |    Rate    |   L2 
Velocity    |   Rate
-----------------------------------------------------------------------------------------
           2           |  2.570197e-03  |                | 1.433416e-03 |
           3           |  5.152276e-04  |    2.319   | 2.951068e-04 |   
2.280
           4           |  1.121537e-04  |    2.200   | 6.326037e-05 |   
2.222
           5           |  2.590115e-05  |    2.114   | 1.422224e-05 |   
2.153

Learned that one needs to always be vary of dimensions.

Thanks for the comments.
