Hi,<br><br>Using mercurial, I get this warning during simulations :<br><br clear="all">INFO (CarpetReduce): Simulation domain volume: 170368000<br>INFO (CarpetReduce): Reduction weight sum:     170367999.880642<br>WARNING level 1 in thorn CarpetReduce processor 0 host tachyon2974<br>

  (line 120 of /home01/r632kgw/jakob/CactusP/arrangements/Carpet/CarpetReduce/src/mask_test.c): <br>  -&gt; Simulation domain volume and reduction weight sum differ<br><br>Simulations seem to run okay though. What is causing this warning and is it serious or can I just ignore it?<br>

<br>Cheers,<br>Jakob<br><br>
