Recent work on the complete wetting transition for three-dimensional systems
with short-ranged forces has
emphasized the role played by the coupling of order-parameter
fluctuations near the wall and depinning interface.
It has been proposed that an effective two-field
Hamiltonian, which predicts a renormalisation of the wetting parameter,
could explain the controversy between the RG analysis of the capillary-wave
model and Monte Carlo simulations on
the Ising model. In this letter results of extensive Monte Carlo simulations
of the two-field model are presented. The results are in agreement with
prediction of a renormalized wetting parameter .
