Group convection_boxStRfCs2

Overview

The group is configured with:

coarsening_fraction: [0.2]

refinement_fraction: [0.3, 0.5, 0.7]

The group is tested with:

The group is genearated with extra settings:

initial_global_refinement: 3

Following the convection_boxStRfCs, additional group to test this, varying the value of refinement fraction

for case with Rf = 0.3, the heat flux has a range between 4.8848730 and 4.90762091.

for case with Rf = 0.5, the heat flux has a range between 4.88398267 and 4.89364336.

for case with Rf = 0.7, the heat flux has a range between 4.88401380 and 4.88918416.

Unlike the case convection_boxCF3.000e-01RF3.000e-01, this shows lot of change in the layout

From previous understanding, we have set the coarsening factor to smaller value, this should alleviate the problem. But it seems it's not the case.
