Hello Ian, > In this case, there is no final error message and abort, unlike in > the case of partially-read gridfunctions.

There is a level 2 warning about the non-read in variables so it should not go unnoticed (in theory at least).

They would be whatever Carpet or the memory allocator initialized them to. CCTK_Initial does not run (normally) during checkpoint recovery. You can have CCTK_Initial run *before* checkpoint recovery (with values in the recoverd variables overwritten by the recovered values) by setting Cactus::recovery_mode to "relaxed" (see flesh/src/param.ccl). This may be what you had in mind. Yours, Roland -- My email is as private as my paper mail. I therefore support encrypting and signing email messages. Get my PGP key from http://keys.gnupg.net.
