Incompressible Navier-Stokes? If so, the following is a very good
setting ILUT parameters to get the system to solve (it contains a
the ILUT parameters):
"Iterative solvers and preconditioners for fully-coupled finite element
formulations of incompressible
fluid mechanics and related transport problems"
