<div>A refinement hierarchy needs to fulfil certain properties. These are enforced in a round-robin manner until a fixed point is reached. Carpet attempts to do so ten times, then gives up assuming there is an internal inconsistency. The message that a second
round is necessary is harmless. This should not be a warning -- this should instead be an informational message only.</div>

<div>Hi All,</div>
<div><br>
</div>
<div>My BBH simulation produces warnings that look like this:</div>
<div><br>
</div>
<div>WARNING level 1 from host <a href="http://srvslshpc605.uct.ac.za" target="_blank">
srvslshpc605.uct.ac.za</a> process 8</div>
<div> while executing schedule bin (none), routine (no thorn)::(no routine)</div>
<div> in thorn CarpetRegrid2, file /opt/exp_soft/EinsteinToolkit/<wbr>Cactus/configs/ET/build/Carpet<wbr>Regrid2/regrid.cc:389:</div>
<div> -> Could not enforce grid structure properties in this round, starting another round</div>
<div><br>
</div>
<div>Could anyone tell me what this means and how to fix it?</div>
<div><br>
</div>
<div>Thanks,</div>
