Novel high performance numerical solution techniques for RCS computations – TECSER

Submission summary

The TECSER project is concerned with the numerical simulation of
frequency domain electromagnetic wave propagation. It addresses
several numerical, algorithmic and computer science related issues
which are here studied by considering innovative technologies and
strategies, the objective being to pro pose solutions techniques
particularly well adapted to modern high performance computing
platforms. The target applications that will be used for
demonstrating the capabilities of the numerical methodologies
resulting from the research and development activities planned in the
project are linked to electronic warfare (propagation problems
involving complex materials and scattering problems for RCS
computations) on one hand, and bioelectromagnetics (propagation
problems modeling the exposure of humans to electromagnetic waves and
the numerical evaluation of the SAR in human tissues) on the other
hand. In particular, for defense applications, this project is in the
same vein as the former research and development works undertaken by
EADS (Innovation Works, whi ch is also a Partner of the present
project, and Astrium ST) and the CESTA center of CEA, entitled «
Simulation haute performance de phénomènes de propagation d’ondes »
which have been awarded the « Science et défense 2009 » prize. Similar
applications a re considered here but the TECSER project will adopt an
innovative theoretical and methodological approach which clearly
defines the natural sequel of the above-mentioned works that have
already been recognized by DGA. The originality of the project is t o
consider simultaneously three research directions and to target
innovative methodological contributions in view of the numerical
simulation of very large - scale electromagnetic wave propagation
problems involving irregularly shaped objects and structures and
complex (heterogeneous, anisotropic) materials. More precisely, these
methodological contributions will concern (1) the discretization of
the three - dimensional time - harmonic Maxwell equations, (20 the
solution of large sparse and complex coefficients algebraic systems of
equations and, (3) the development of numerical algorithms and
software adapted to modern, massively parallel, high performance
computing systems. For the realization of the associated research and
development works, the TECSER project will rely on a consortium of
partners organized around three project-teams of INRIA’s research
centers localized in different geographical sites. Two industrial
partners will also actively participate to the project: the Innovation
Works (IW) research center of EADS, and the Nuclétudes company which
is a subsidiary of EADS Astrium. The researchers and engineers acting
in the project possess complementary expertises on the three
above-mentioned research axes.
