[Users] Simulation domain volume and reduction weight sum differ

[Erik Schnetter]

There are three possible causes for this warning:

1. An internal error in Carpet (that's why the warning was put in)
2. An inconsistent grid structure setup, e.g. near a symmetry or an
outer boundary, i.e. an error in a parameter file
3. You are using thorn CarpetMask to exclude a horizon from reductions

In case 3 the warning is harmless (and should not be there -- sorry).
