[petsc-users] extract preconditioner matrix

[김성익]

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 preconditioner matrix created in Petsc?

3. Is this possible to separate preconditioning & solving procedure to
check the result of each process in Petsc??


Thanks,
Hyung Kim
