Comments
- This option can be used with ALE or
Eulerian modeling.
- This
coefficient has no influence if Taylor Galerkine
(/UPWM/TG (Obsolete)) or Streamline Upwind
(/UPWM/SUPG (Obsolete)) formulation is
defined, except for multi-material LAW51 (/MAT/LAW51 (MULTIMAT)).
-
is a coefficient for multi-phase law.
is only available for multi-material LAW51
(/MAT/MULTIMAT).
=1 is stable, but diffusive.
=0 is less diffusive, but might be
unstable.
