Group convection_boxStRfCs
Overview
The group is configured with:
refinement_fraction: [0.4, 0.6, 0.8]
The group is tested with:
complement_refine_coarse: [1]
The group is genearated with extra settings:
test adaptive refinement and 'refraction' and 'coarsening' factor
For this group, I choose different refraction factor and assign a complement coarsening factor to the refraction factor.
Develop of mesh at the start of convection
The case with the highest refraction factor develops a refined region roughly matches the boundary region. While the other two doesn't really capture the boundary region.
Issue: Unstable meshes
For all three cases, the meshes doesn't become stable when the temperature is stable.
Issue: misterious coasrsening
At around 230 step, the mesh for the case convection_boxRF4.000e-01testCRC1 is all coarsened.
