Digimat-FE is the tool used on the microscopic level to obtain an in-depth view into the composite material by the direct investigation of Representative Volume Elements (RVEs).

Digimat-FE is a Tool of Digimat software to compute composite materials' performances using the Finite Element homogenization method.


Digimat-FE generates realistic (stochastic) Representative Volume Elements (RVEs) for a large variety of material microstructures and can as well rely on external geometric microstructure description such as micro CT-scan or molecular dynamic results.

Based on material input and the microstructure definition, a finite element model is built and run. Various solvers are accessible to perform simulations including an embedded FEA solver, a Fast Fourier Transform solver and external solvers. The results of the FE analysis is post-processed in the sense of probabilistic distribution functions that give detailed insight into the RVE. Mean homogenized values are computed and can be used in subsequent FE analysis on the structural part level.

Digimat Finite Element technology is an End-to-end Tool for composite materials simulation:

A complete end-to-end solution has been implemented in Digimat®. It allows performing all the different steps needed to obtain a complete FE analysis - starting from the material data. For example for woven composites those steps are:

  • Extraction of the material data from the datasheet
  • Mean-field homogenization of the yarns
  • Generation of a geometry of a unit cell
  • Generation of a RVE
  • Voxelisation
  • FE model definition and application of periodic boundary conditions
  • Solving the FE analysis
  • Post-processing the outputs of the FE analysis
Digimat enables us to perform in depth studies of complex and realistic microstructures. As an investment in the future we base our simulation approach on the Digimat software, both for our research and the education of a new generation of simulation engineers who will be experts in the modeling of material."
