Eldorado Hotel and Spa
Workshop objective: The
purpose
of
this
workshop
is
to
discuss
methods
of
integrating
Uncertainty
Quantification
(UQ)
with
Multiscale
Materials
Modeling
(MMM)
and
Analysis.
While
Multiscale
integration
has
long
been
a
theme
in
the
materials
modeling
community,
particularly
emphasized
in
the
ASC,
PSAAP
and
NEAMS
programs,
fully
integrated
simulations
are
quite
rare.
The
typical
paradigm
is
to
establish
a
multilevel
hierarchy
(e.g.,
atomistic,
single
crystal,
polycrystal
and
continuum)
and
to
pass
parameters
between
the
levels,
especially
from
the
lower
length
scale
upwards.
Still
the
lower
length
scale
simulations
are
performed
on
fairly
homogeneous samples
so
that
data
extraction
is
simplified.
Consequently,
the
full‐range
of
variations
and
uncertainties
from
gradients
and
heterogeneities
of
real
materials
may
not
be
adequately
explored.
From
a
top‐down
approach,
it
is
expected
that
the
lower
lengths
scales
will
be
capturing
the
effects
of
the
internal
fluctuations
and
variations
of
the
materials.
However,
the
metrics
used
to
describe
these
heterogeneous
characteristics
are
rather
primitive,
so
that
one
does
not
have
a
sound
foundation
of
relating
a
sufficient
number
statistically
representative
samples
to
some
desired
tolerance
of
the
results.
Understanding
the
sensitivity
of
the
results
to
such
a
distribution
of
realistic
samples,
and
especially
properly
accounting
for
the
weighting
of
extreme
events
in
the
overall
material
that
might
be
controlling
the
effective
“bulk”
response
are
topics
that
have
not
been
properly
addressed.
The
tools
of
UQ
to
characterize
these
and
to
more
completely
relate
information
from
experimental
studies
on
in completely
characterized
samples
need
to
be
more
fully
developed.
The
goal
of
this
workshop
is
to
bring
together
experts
in
various
aspects
of
Materials
Modeling
and
Uncertainty
Quantification
to
discuss
these
issues.
One
fundamental
impediment
is
communication
of
what
information
the
various
techniques
work
with
and
generate,
and
what
dimensionality
(complexity)
of
data
they
can
effectively
handle.
The
framework
is
to
have
alternating
sessions
of
Materials
Modeling
and
Uncertainty
Quantification,
with
all
members
of
the
workshop
participating.
Each
session
will
be
lead
off
by
a
plenary
speaker
who
should
frame
the
fundamental
topics
of
the
session
in
a
manner
that
can
be
appreciated
by
the
entire
audience.
Subsequent
talks
in
the
session
should
elaborate
on
these
issues.
The
session
would
be
concluded
by
a
general
discussion
of
the
topics,
lead
by
a
selected
panel
that
should
identify
paths
forward
for the
integration
of
UQ
and
MM.
The
output
of
the
workshop
will
be
a
white
paper
that
summarizes
these
discussions.
The
session
chairs
and
panel
leads
(and
other
interested
participants)
will
be
begin
drafting
these
summaries
on
the
last
afternoon
of
the
workshop.
The
final
document
will
be
distributed
to
all
of
the
participants.
Registration for the workshop is online. Information about the hotel is available here.
