[Libmesh-users] Wrong with the option "-pc_type iilu -pc_ilu_levels 4"

[Shengli X. <she...@gm...>]

Hello,
When the program is runned with the option "-pc_type ilu -pc_ilu_levels 4",
the result is:

Linear solver converged at step: 5000, final residual: 1.60729
WARNING! There are options you set that were not used!
WARNING! could be spelling mistake, etc!
Option left: name:-pc_ilu_levels value: 4

I don't know what's wrong with my libmesh.
Could you tell me what is wrong?
