DIGIMU® is the result of research projects conducted for more than ten years at the CEMEF (Material Forming Center) in collaboration with many industrial stakeholders from the metallurgy, aeronautics and nuclear sectors. The two pillars of DIGIMU® software development are the extensive experimental work and the constant improvement of existing numerical methods, which allow CEMEF to be at the forefront of world research in the field.

The full-field approach proposed by DIGIMU® has two main objectives:
DIGIMU® generates digital polycrystalline microstructures representative of the material's heterogeneities (compliance with the topological characteristics of the microstructure). The boundary conditions applied to the REV are representative of that experienced by a material point at the macroscopic scale (thermomechanical cycle of the considered point). Based on a Finite Elements formulation, the various physical phenomena involved during metal forming processes are simulated (recrystallization, grain growth, Zener pinning due to second phase particles, etc.).
Fully automated adaptive anisotropic meshing:
In order to improve digital precision and to reduce computation times, the software is capable of providing a precise description of the interfaces (grain boundaries) while using an appropriate number of elements thanks to a fully automated anisotropic meshing and remeshing adaptation technology.
Automatic mesh refinement in the direction normal to the grain boundaries (anisotropic meshing)
Fully parallelized calculations:
Like all other TRANSVALOR software, DIGIMU® is built around an optimized high-performance architecture capable of running on one or more cores in order to guarantee maximum processing power.Some features have also been recently integrated into DIGIMU®:
In the short term:
In the long term:
Our software provides assistance in the development of high performance alloys and parts through the prediction of microstructural phenomena.
DIGIMU® allows to understand which metal alloys to use and the impact of the treatments applied to them.
Simulation helps to control industrial risks related to the microstructure of the materials and their applications.
Anticipate your grains size driven by capillarity forces, and stored energy gradient at the interfaces.
Simulate polycrystal deformations, hardening and recovery, nucleation, and following nuclei growth. Follow static, dynamic and postdynamic recrystallization.
Import your models to define your own hardening, recovery and nucleation laws.
Let’s work together hand in hand. DIGIMU® users get the support they need when using our software.
