Is there a way to, e.g. call CarpetIOHDF5, from the middle of a subroutine -- apart from "scheduling" the output?

That should be possible using CCTK_OutputVarAsByMethod, see below.

See https://bitbucket.org/ianhinder/substepoutput/src/68caba7fa824/src/substepou... for an example.

Hey guys, Frank recommended CCTK_OutputVarAsByMethod, but gave code for CCTK_OutputVarAsBy. When I use the latter, the code segmentation faults.

Ian, I couldn't find where you set the variable output_method in your example. Where does that definition go?

CCTK_OutputVarAsByMethod(cctkGH, fullvarname, output_method, alias_name);

Thanks, Scott

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
