Hi guys:

Does anyone know what is the linear solver used in CFX ?
Is that a implicit Krylov subspace type solver or some other ?

I have searched on Google about that but got no satisfactory answers.......

This is described in the documentation. Let me quote:
ANSYS CFX uses a Multigrid (MG) accelerated Incomplete Lower Upper (ILU) factorization technique for solving the discrete system of linearized equations.
