 Reporter:  knarf   |       Owner:  eschnett
     Type:  defect  |      Status:  new     
 Priority:  minor   |   Milestone:          
Component:  Carpet  |     Version:          
 Keywords:          |  
--------------------+-------------------------------------------------------
 The attached parfile creates a grid using CarpetRegrid2 (hg version),
 which CarpetReduce later warns about:

 INFO (CarpetReduce): Simulation domain volume: 4096
 INFO (CarpetReduce): Reduction weight sum:     4468.125
 WARNING[L1,P0] (CarpetReduce): Simulation domain volume and reduction
 weight sum differ

 The grid info is:

 INFO (Carpet): Grid structure (superregions, grid points):
    [0][0][0]   exterior: [0,0,0] : [21,21,21]   ([22,22,22] + PADDING)
 10648
    [1][0][0]   exterior: [3,3,3] : [40,40,40]   ([38,38,38] + PADDING)
