Group convection_boxStRf

Overview

The group is configured with:

refinement_fraction: [0.4, 0.6, 0.8]

strategy: temperature

The group is tested with:

The group is genearated with extra settings:

test refinement factor

Number of cells

with no coarse factor, the mesh tends to be refined through time.

causation

This has to do with the fact that the error is related with $$d^n$$ which results in larger error in larger cell.

solution

• set additional time refinememnt
• set coarsen factor
