[petsc-users] LU vs. ILU

[Verena Kuhlemann]

Hello,

I am somehow confused with the usage of PCLU and PCILU ind PETSc.
It seems as there are the same options to choose from for both.
In particular, if I use PCLU and PCFactorSetFill(pc,5)
don't I end up with an incomplete LU factorization?
If I use PCLU with no other options set, will the
factorization be complete?

Thanks,
Verena
