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

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.

Thank you Erik! That's good news.
What happens if Carpet doesn't manage to enforce the properties after ten rounds? Does the simulation abort, or is a different kind of warning produced?

If Carpet cannot create a self-consistent grid hierarchy, then it will abort.

Hi Erik
It sounds like we should use a higher warning level here. Which level would you suggest?
Most simfactory run scripts use 3 as default. Maybe 4 or higher?

This should not be a warning at all, but should rather be an informational message only.
