I'm work on FEM (especially for solving contact mechanics).
In contact mechanics, original global jacobian matrix has nondiagonal
dominance in some rows.
I want to remove this effect(nondiagonal dominance) by using some
techniques.
Because I saw the many references that nondiagonal dominance is

Hello,
I tried to find the way to adapt my own preconditioner.
In other words, I want to apply and solve a new preconditioner rather than
using the existing one in Petsc.
So, my questions are as below
1. Is this possible to adapt my own preconditioner??
2. Also is it possible to extract
