Front Tracking

3D FrontTier structures.

Untangling: before (a) & after (b).

Refraction near glancing incidence.
FronTier accurately describes the
evolution of fluid interface across which
physical quantities are discontinuous. It is
extended to 3D to solve the acceleration
driven Rayleigh-Taylor and and
Richtmyer-Meshkov instabilities.
A movie shows the formation of a bubble
in the nonlinear regime of R-T instability.
Another movie shows the evolution of
a supersonic turbulent jet and its interaction
with a shock wave as the reflection
of the bow shock from an external wall.
