We use the incremental unknowns method in conjunction with the iterative
methods to approximate the solution of the nonsymmetric and
positive-definite linear systems generated from a multilevel
discretization of three-dimensional convection-diffusion equations.
The condition numbers of incremental unknowns matrices  associated
with the convection-diffusion equations and the number of iterations
needed to attain an acceptable accuracy are estimated. Numerical
results are presented with two-level approximations, which
demonstrate that the incremental unknowns method when combined with
some iterative methods is very efficient.},
