Hi Yingjie,
For finite difference method, there are a lot of example in PETSc. For
instance,

For linear eigenvalue problems, there is a list of examples at
Thank you, Fande.
I've seen you in moose usergroup before.
I've just learned about SLEPC, and I wonder if I want to do neutron
eigenvalue calculations and use finite difference to discrete grids, would
it be difficult to implement it in SLEPC? Is there such an example(finite
difference + linear
I have implemented this algorithm in SLEPC. Take a look at this example

The motivation of the algorithm is also for neutron calculations (a
moose-based application).

Dear Petsc developer:
Hi,
Thank you very much for your previous reply, they really helped me a lot.
I've been doing neutron calculations recently, and I want to use the power
Iteration method to calculate the neutron flux, essentially to solve linear
equations, but after each solution is done,
