Title
Computational tools for coupled magma/mantle dynamics
Abstract
Very
little
is
known
about
the
interior
structure
of
the
earth
and
the
processes
going
on.
To
understand
more
about
these
processes,
geo-scientists
have
developed
many
models
describing
for
example
tectonic
plate
movement
and
magma
flow
through
the
mantle
matrix.
The
two-phase
equations
describing
coupled
magma/mantle
dynamics
describe
large
scale
features
of
tectonics
plates
down
to
small
scale
features
of
melt
localization.
Computational
challenges
arise
due
to
this
multiscale
behaviour:
large
domains,
high
resolution
grids
and
many
time
steps
are
required
to
model
magma/mantle
dynamics.
In
the
first
part
of
my
talk
I
will
discuss
the
development
of
computational
tools
I
am
working
on
for
the
two-phase
flow
equations.
I
will
discuss
a
new
preconditioner
I
have
developed
and
show
3D
numerical
simulations
that
I
will
compare
to
observations
from
laboratory
experiments.
In
the
second
part
of
my
talk
I
will
discuss
my
future
research
plans.
These
range
from
new
Discontinuous
Galerkin
finite
element
methods
on
time
dependent
domains
to
solvers
and
software.
