That should be possible using CCTK_OutputVarAsByMethod, see below.


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


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

           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.

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