Log PETSc solver output to file
Dear Firedrake Team, I'm PhD student and recently started to use Firedrake for my work. I'm implementing a FEM simulation and wanted to log the convergence of the PETSc KSP solver (e.g. residuals) in a log-file for later analysis. Maybe this is trivial, but unfortunately I did not find any information in the example codes on the firedrake homepage, the mailing list and GitHub Issues/Discussions. Could you please help me with this problem? Thanks in advance. All the best, Aaron P.S. I'm working with the Firedrake Docker Image 2024-07.

-log_view gives the performance, but for the residuals you want -ksp_monitor. Thanks, Matt On Tue, Aug 13, 2024 at 6:15 AM Cotter, Colin J <colin.cotter@imperial.ac.uk> wrote:

Urgh I misread. Yes, for residuals use the petsc options for the solver, following <https://www.firedrakeproject.org/solving-interface.html#id7> Solving PDEs — Firedrake 0+unknown documentation<https://www.firedrakeproject.org/solving-interface.html#id7> firedrakeproject.org<https://www.firedrakeproject.org/solving-interface.html#id7> [icon.ico]<https://www.firedrakeproject.org/solving-interface.html#id7> add “ksp_monitor”: None to the solver-parameters dictionary for the solve.
