Three-dimensional Sedov blast on a
hexahedral mesh. |
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.
