ImpressionThe DIGIMU ANR Industrial Chair is one of five projects selected by ANR in their « Industrial Chairs – 2016 Edition » program. The DIGIMU Chair, handled by Armines MINES ParisTech, is co-funded by ANR and the industrial consortium composed of the companies ArcelorMittal, Framatome, ASCOMETAL, AUBERT & DUVAL, CEA and SAFRAN. This Chair is a project of the DIGIMU consortium constituted by the previous cited partners along with  TIMET, CONSTELLIUM and TRANSVALOR companies. Moreover this ANR industrial Chair is supported by the PNB (Pôle de l’Industrie Nucléaire – Nuclear Industry Cluster) and Astech (Aeronautics / Space) competitiveness clusters.

What is the aim of DIGIMU?

DIGIMU aims to develop an innovative global framework for the simulation of microstructural changes during forming processes.
It is also the name of the software developed by the company TRANSVALOR in collaboration with the CEMEF and industrial partners of the DIGIMU Chair and consortium, which was first released commercially in 2016. This software is based on numerical developments in metallurgy made by the MSR (Metallurgy Structure Rheology) and MSM (MultiScale Modeling) CEMEF MINES ParisTech teams. All the numerical developments of the Chair will contribute to the development of this software.


Countless products involved in our every-day life rely on vital metal parts. Optimizing these parts requires a knowledge of how material properties change during forming operations. Although the understanding of the underlying metallurgical phenomena has improved thanks to the continuous progress of experimental facilities, the interest for increasingly fine and predictive simulations has been recently growing. In this emerging context of « digital materials science », the DIGIMU Chair and consortium has two main objectives. The first concerns the development of an efficient multiscale numerical framework adapted to these questions. The second relates to the optimization of these techniques in terms of numerical cost and their validation by the industrial expertise at the heart of the DIGIMU consortium. For these digital tools, which are still quite news, it’s a question of going beyond the usual framework of « simulation for industrialists » and moving towards « simulation by industrialists ».

Moreover, if the DIGIMU Chair is mainly dedicated to recrystallization and solid-solid phase transformations for metallic materials. The transverse numerical framework developed by the DIGIMU consortium presents also large potential for the modeling of other physical mechanisms at the microscale (ductile damage, self-diffusion mechanisms as globularization or sintering, fracture…) and for a large range of materials (metallic or polymer composites, granular materials, …).
