redirect PETSc snes output to a file instead of terminal

0 votes

Hi all,
When I use the petsc snes solver with report = true, I get lots of good info spewed in my terminal. Does anyone know a way to redirect that to a log file instead?

Thanks

>>> python yourproblem.py > output.txt

Thanks, but I only want the PETSc output to go into a file, not all the output. Basically, I don't want to always see the PETSc output (and have it overwhelm the other program output), but have it available if I need to check why the solver behaviour.
