IMACS

Innovation@Work in Numerical Modelling

IMACS 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 15 years a portfolio of services and specialized products for numerical simulation, with focus on vibro-acoustics and electromagntics, and provides its products and services to leading automotive and aerospace companies.

Innovation in numerical modelling is at work at IMACS.

Time Domain BEM vibro-acoustic solver SONATE©


Building on research lead at the Centre de Mathématiques Appliquées of the Ecole Polytechnique (CMAP) under supervision of Prof. Jean-Claude Nédélec, IMACS has been the first company to 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 existing 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.
