[petsc-users] How to change KSP tolerance during SNES steps

[behzad baghapour]

Dear All,

I set SNES with -snes_ksp_ew to solve the system with inexact method. I
want to reset the SNES into exact Newton with changing the KSP rtol at
final iterations (in full Newton phase). How can I reset the KSP tolerance
after specific iterations of SNES?

Regards,
BehZad
