#1417: Fixed refinement levels break AMR
 Reporter:  coryell@…            |       Owner:  eschnett           
     Type:  defect               |      Status:  new                
 Priority:  major                |   Milestone:                     
Component:  Carpet               |     Version:  development version
 Keywords:  CarpetRegrid2        |  
 CarpetRegrid2's "fixed box" functionality apparently prevents adaptive
 mesh refinement from occurring. When the parameter
 CarpetRegrid2::num_centres is set to 1, refined levels near increased
 level_mask do not appear, but they do if num_centres is set to 0. I have
 included a modified version of the AMRToy thorn whose only purpose in
 these tests is to set the level_mask in an annulus shape with larger
 radius than that of the fixed box. I have also included three parameter
 files, one in which there is only fixed-box refinement, one in where there
 is only AMR, and one in which there is both. In the test where there is
 both, I only observe the fixed-boxes showing up. The resolution of these
 parameter files can be increased to get better-defined AMR, but this low
 resolution still demonstrates the problem.
