Advances
of
the
reserach work presented in the previous
page
are proposed in [1].
The variational
multiscale (VMS) analysis has
been
used to develop a new
stabilization appraoch, which was
also combined
with a globally conservative
predictor/multi-corrector time
integrator. Stable time step
bounds and
formal second-order accuracy
estimates for the resulting method
are
derived, by means of the
von Neumann stability
analysis.
