Group convection_boxAdaptiveRefinement

Overview

The group is configured with:

initial_global_refinement: [3]

refinement_fraction: [0.6, 0.8, 1.0]

The group is tested with:

The group is genearated with extra settings:

Number of cells, computational time, statistic results

For Refinement fraction = 1.0, there are 4^2 = 64 cells to start with. After t = 0.2 there are 256 cells. After t = 0.3 there are 1024 cells. After t = 0.4 there are 4096 cells. It takes 1744 steps to reach t = 0.5 Heat flux2 = -4.88441046, Heat flux3 = 4.88441046, RMS Velocity = 42.8649456

compare to the results we have in group Group convection_boxGlobalRefinement, this is better than Global refinement = 4, but with more time steps(1744 > 1000)

For Refinement fraction = 0.8, there are 4^2 = 64 cells to start with. After t = 0.2 there are 148 cells. After t = 0.3 there are 394 cells. After t = 0.4 there are 1060 cells. It takes 1678 steps to reach t = 0.5 Heat flux2 = -4.88466479, Heat flux3 = 4.88466479, RMS Velocity = 42.8660622

this is a litter worse than Global refinement = 4.

For Refinement fraction = 0.6, there are 4^2 = 64 cells to start with. After t = 0.2 there are 112 cells. After t = 0.3 there are 238 cells. After t = 0.4 there are 514 cells. It takes 1594 steps to reach t = 0.5 Heat flux2 = -4.88556725, Heat flux3 = 4.88556725, RMS Velocity = 42.8655231
