Subject: [EXTERNAL] Re: [petsc-users] Redirecting petsc output
Philip,
There a variety of techniques. Some of the command line options take an optional viewer name where the output can be redirected. For example
-ts_monitor ascii:filename or -ts_view ascii:filename see https://petsc.org/release/docs/manualpages/Viewer/PetscOptionsGetViewer.html for more details
It is also possible to change all stdout from PETSc to a different file by setting PETSC_STDOUT = fopen(...)

Is there a way to customize how petsc writes information? Instead of writing to stdout (for example: 0 TS dt 0.1 time 0.), what if we want to log that message to a file other output from Xolotl? I'm assuming there are multiple ways of getting this result. What's common practice with petsc folks?
