I assume there is a certain mechanism that you are using in your parameter file to set and update the position and shape of the refined region. It is probably this mechanism that is failing.

Which mechanism is this?

Hi,

When running a BNS simulation, we occasionally run into the following error message:

ERROR from host node1 process 0 in thorn CarpetRegrid2, file /home/wbark/Software/EinsteinToolkit/Cactus/configs/sim/build/CarpetRegrid2/regrid.cc:80: -> The radius of refinement level 7 of region 3 is [-1,-1,-1], which is not non-negative

Is there a general fix for this that we are missing?

Thank you!!

cheers, Wayne
