That should be possible using CCTK_OutputVarAsByMethod, see below.

Frank

int istat = CCTK_OutputVarAs (const cGH *cctkGH,
                              const char *variable,
                              const char *alias);

Parameters

istat    return status
cctkGH   pointer to CCTK grid hierarchy
variable full name of variable to output, with an optional options stri
alias    alias name to base the output filename on

Discussion
           The output should take place if at all possible. If the
           appropriate file exists the data
           is appended, otherwise a new file is created. Uses alias as
           the name of the variable
           for the purpose of constructing a filename.


Errors
positive the number of IO methods which did output of variable
0        for success
negative if no IO methods were registered
