Mathematics for Innovative Companies
is for "Ingénierie MAthématique et Calcul Scientifique"
IMACS is a research and
technology provider with
activities centered on scientific computing and mathematical
engineering. IMACS originated as a spin-off from Ecole
Polytechnique, Centre de Mathématiques Appliquées. IMACS offers
products and services ranging from consultancy to software development,
deployment, maintenance and support to end users.
IMACS has developed over the last
20 years a portfolio of
services and specialized products for numerical simulation and
statistical analyses. IMACS provides its products and
services to leading companies in
automotive, aerospace and defence, energy...
Innovation in numerical modelling
and High Performance Computing
is at work at IMACS.
New Numerical Methods
and HPC solvers for demanding applications
Development of new numerical methods and their parallel implementation:
Element Methods (BEM): new formulations in the time and frequency
solvers: H-matrix, Fast Multipole Method (FMM) and their coupling;
and multi-physics couplings in linear and nonlinear cases (DGM, FEM,
BEM, TLM, circuit solvers...;
for CAD/CAE link, simplification, meshing...
meshing procedures based on a
poteriori estimates for FEM and BEM;
for data analysis, reliability, sensitivity, meta-modelling,
for Industrial Applications
Development of new methodologies and computation chains:
modelling: innovative acoustic liners and CFRP composites for aeronautic industry , meta-materials for antennas and
modelling of complex systems: electromagnetic compatibility (EMC),
lightning indirect effects (LIE), high-intensity radiated fields
(HIRF), antenna modelling and antenna siting, radar cross section
modelling in frequency domain ou time domain (retarded potentials) ;
testing (NDT) based on eddy current or ultrasound.
a unique Time Domain BEM
solver for vibro-acoustics
Building on research lead at the
Centre de Mathématiques Appliquées of the Ecole Polytechnique (CMAP)
supervision of Prof. Jean-Claude Nédélec, IMACS has been the first
develop and propose a robust Time Domain BEM solver, providing a
new tool SONATE©
used in industry for simulations in acoustics, and
which proves to
be much more efficient and precise for multi-frequency problems than
tools. Following the success of SONATE© in automotive applications (PSA
Peugeot-Citroën and Renault), a partnership has been signed with LMS
International, the world leader in acoustic simulations. SONATE© is integrated
in the CATIA V5 based platform LMS Virtual.Lab® since Rev9, and
distributed worldwide by LMS Intl now Siemens Industry Software.
