Hi,
If I add a thorn to a simulation part-way though, its Cactus variables won't be
present in the checkpoint file on the first recovery. The code which detects
this is in Carpet/CarpetIOHDF5/src/Input.cc and the warning is:
CCTK_VWarn (2, __LINE__, __FILE__, CCTK_THORNSTRING,
"variable '%s' timelevel %d has not been read",
fullname, tl);
In this case, there is no final error message and abort, unlike in the case of
partially-read gridfunctions. Is this a deliberate decision, because for
partially-read gridfunctions the results are definitely wrong, whereas not
reading variables at all might be OK? In my particular case, the variables are
scalar integers. What value would the variables have in this case? Does
Carpet initialise variables to 0? I seem to see 0, but haven't checked
carefully.
