Comment (by coryell@…):

 Additional debugging information: The grid structure before and after the
 AMR step occurs (line 302 in CarpetRegrid2/src/regrid.cc)


 Fixed-boxes only:

 Before AMR: Refinement level 0: regions are
 bboxset<CCTK_INT4,3>:{size=97336,setsize=1,set=[([0,0,0]:[360,360,360]:[8,8,8]/[0,0,0]:[45,45,45]/[46,46,46]/97336)]}
 Before AMR: Refinement level 1: regions are
 bboxset<CCTK_INT4,3>:{size=512,setsize=1,set=[([166,166,166]:[194,194,194]:[4,4,4]/[41,41,41]:[48,48,48]/[8,8,8]/512)]}
 < AMR does not occur >

 Both fixed-boxes and AMR:

 bboxset<CCTK_INT4,3>:{size=97336,setsize=1,set=[([0,0,0]:[360,360,360]:[8,8,8]/[0,0,0]:[45,45,45]/[46,46,46]/97336)]}
