for minisymposium no. 42 entitled
Computational Electro-Magneto-Hydro-Dynamics (EMHD)
http://www.iacm-eccomascongress2008.org/admin/files/fileabstract/a42.pdf
World Congress on Computational Mechanics and IACM-ECCOMAS08
Venice, Italy, June 30 - July 5, 2008

Electro-Magneto-Hydro-Dynamics (EMHD) addresses all phenomena related
to the interaction of electric and magnetic fields with electrically
conducting or magnetic fluids. Electric and magnetic flow control, for
example, is a challenging area of mathematical and engineering
research with many applications such as the reduction of drag, flow
stabilization in order to avoid transition to turbulence, tailored
stirring of liquids, pumping using travelling EM waves, and many
others. The application of electric and magnetic fields in branches
such as crystal growth, solidification, metal casting, welding,
fabrication of nanofibers, fabrication of specialty composites and
functionally graded materials, or ferrofluids is recently of growing
interest. Fully coupled EMHD systems, that is, situations where the
flow-field is influenced by the electric and magnetic fields and where
these fields are in turn influenced by the flow-field, are challenging
research subjects with applications in geo- and astrophysics (dynamo,
magneto-rotational-instability, etc.). Numerical simulations of
complex processes (growth of single crystals, metal casting processes,
aluminium electrolysis, etc.) require sophisticated tools for coupled
fluid flow - heat/mass transfer - electromagnetic field systems. In
summary, computational EMHD is a vital subject of recent research with
a long list of interdisciplinary applications and scientific problems.
Under the title of "Computational Electro-Magneto-Fluid-Dynamics
(EMFD)" the topic successfully participated as minisymposia at WCCM VI
and WCCM VII. Recently, EMHD received a major funding, e.g., in
Germany and China. On European scale the recent COST-Action P17 might
be mentioned as a clear indicator that EMHD activities are going to be
intensified in several European countries. A dedicated minisymposium
on "Computational EMHD" will ideally fit into the development of the
field both on European as well as international level.

Metamodels for High Dimensionality Response Surfaces
in Multiobjective Optimization
http://www.iacm-eccomascongress2008.org/admin/files/fileabstract/a45.pdf
World Congress on Computational Mechanics and IACM-ECCOMAS08
Venice, Italy, June 30 - July 5, 2008

When performing large scale optimizations involving many simultaneous
and often conflicting objectives, hundreds and even thousands of
design variables, and dozens of equality and inequality constraints,
and where each objective function evaluation is very costly, the only
practical method of reducing the overall computing effort is to use
metamodels or lower fidelity models. The most popular such method is
to perform analytical fits of the available high fidelity data thus
creating multidimensional response surfaces. Current methods for the
creation of the response surfaces are based on algorithms such as
linear regression, radial basis functions, wavelet based neural
networks, self-organizing maps, graph theory, Kriging, etc. All of
these methods suffer from rapidly decreasing accuracy and rapidly
increasing computing time as the number of design variables increases.
Furthermore, most of the currently used methods are not capable of
dealing with irregularities and noise of the realistic design space
topologies which are unknown a priori.
Since optimization is becoming widely accepted in industry when
performing multidisciplinary design involving simultaneously
disciplines such as fluid mechanics, elasticity, heat transfer,
electromagnetism, chemistry, etc., there is a recognized and growing
need for the development of more reliable, accurate and
computationally efficient methods for the automatic construction of
multidimensional response surfaces for hundreds and even thousands of
noisy design variables.
The proposed minisymposium should bring together international experts
on this subject and serve as a perfect event for comparing the
capabilities and drawbacks of conceptually different algorithms and
their hybrid combinations for fitting large dimensionality response
surfaces, thus advancing the fields of large scale multi-objective
optimization and design.

Multidisciplinary optimization problems represent a complex task which
requires outstanding model environments, complex analytical solvers
and powerful optimization techniques, which combined in a reliable way
lead to an effective solution of the problem. From the optimization
point of view, Evolutionary Algorithms methodologies have shown its
evident benefits in simple and multimodal optimization problems due to
their robustness, easy applicability and the fact that they do not
need specialized information such as gradient information or
smoothness of objective functions.
The aims of this mini-symposium is to provide a forum to join
scientists, academicians and practical design engineers in order to
explore, discuss and present recent developments in analysis and
evolutionary optimization techniques with potential applications to
multidisciplinary optimization problems in different engineering
disciplines and in science
In this sense, the proposed minisymposium on application of
evolutionary optimization techniques in multidisciplinary problems
thus offers a unique international forum that should provide an
excellent basis for cross-fertilization of ideas and creation of new
synergistic approaches and methodologies that will combine advances in
computational methods to model and analyze complex problems with
powerful optimization techniques based on evolutionary principles in
order to create more general, robust, accurate and computationally
economical design methods for multidisciplinary applications.
The areas of interests include but are not limited to:
Robust Design, Reliability-Based Design Optimization, Optimization
Methods, Sizing and Shape Design, Topology Optimization,
Multidisciplinary Design Optimization, Design Sensitivity Analysis,
Materials Processing Optimization, Hybrid Optimization Algorithms,
Evolutionary Algorithms (Genetic Algorithms, Evolutionary Strategies
and so on) Managing the Design Process, Optimization with High
Performance Computing, Benchmarking, Testing, and Classification of
Optimization Software

Motivation and purposes.
Methods for the parameter identification through inverse analysis
(namely by minimization of the discrepancy between measured and
computed quantities) are at present spreading in several engineering
and technological fields. In fact, the synergistic integration of
computational and experimental mechanics, which represents the
peculiar feature of inverse analysis, turns out to be fruitful, and
sometimes necessary, in a number of practical situations for a variety
of reasons, namely: the availability of effective ad hoc mathematical
theories and tools; the growing realism and complexity of material
models (with more and more parameters not directly measurable by
standard tests); the deterioration of many socially important existing
structures and the need for their reliable diagnostic analysis before
retrofitting provisions.
The objective of this Minisymposium is to provide an international
forum for presentations and discussion of research results concerning
practical methods centered on inverse analysis, for mechanical
characterization of materials through calibration of their
constitutive models and for diagnostic analysis of existing possibly
deteriorated structures, with reference to representative classes of
engineering and industrial situations.
Items to be dealt with.
Fundamentals: mathematical procedures for constrained minimization of
possibly nonconvex and nonsmooth functions; numerical solution methods
and algorithms (direct search; first and second order minimization
algorithms; mathematical programming); soft computing procedures
(genetic algorithms, artificial neural networks); identification
methods with "batch" use of experimental data; sequential methods such
as Kalman filter and its extensions; statistical processing of
measurement noise and modelling errors; sensitivity analyses of
measurable quantities with respect to the parameters to identify; some
representative and partly innovative experimental techniques related
to parameter identification (indentation, small-punch, atomic force
microscope, laser profilometers, radar and laser monitoring, etc.).
Calibration of material models on the basis of experimental tests:
elasto-plasticity of metals; inelastic and fracture behaviours of
quasi-brittle materials (concrete, ceramics); visco-elasto-plasticity
of polymers; interface models for joints; constitutive modelling of
heterogeneous materials (composites and laminates); assessment of
local constitutive parameters through tests at the macroscale in
average variables: parameter estimation by indentation tests
associated to imprint mapping and by "small punch" tests. Meaningful
applications to engineering problems concerning structural components
in various industries and in microtechnologies. Specifically,
diagnostic analysis of structures based on in situ monitoring and
nondestructive tests: main causes of structural damages (deterioration
phenomena such as aggregate-alcali-reaction in concrete; extreme
loadings); parameters representative of structural damages; typical
equipment for in situ tests and monitoring of structures and
industrial components; sensitivity analysis; inverse analyses to
diagnostic purposes; representative applications to concrete dams,
bridges, monumental structures and industrial components.
