Digimat offers the tool to analyze your multiphase composite materials in an accurate, efficient and easy way!
Digimat-MF is a Tool of Digimat software to compute composite materials' performances
Digimat-MF is the mean field homogenization tool to rapidly compute the macroscopic performance of composite materials from their per-phase properties and microstructure definition. Digimat-MF aims at the realistic prediction of the non-linear constitutive behavior of multi-phase materials taking into account temperature and strain rate dependencies. The composite morphology such as filler content, length, aspect ratio and orientation take full impact on the resulting composite behavior. Digimat-MF is accurate, efficient and very easy to learn and use.
Digimat-MF is used mainly by universities, research institutes and material suppliers, as well as OEMs and Tier1s research departments.
Digimat Mean Field homogenization technology is especially well suited to describe fiber reinforced composites:
- Short fiber reinforced plastics
- Long fiber thermoplastics
- Unidirectional composites
- Woven composites
- Sheet Molding Compound
A broad range of performances can be predicted realistically with Digimat Mean Field homogenization technology :
- Stiffness
- Failure
- Creep
- Fatigue
- Conductivity (thermal & electrical)
The application of Digimat-MF and Digimat-FE paved the way for me to give an insight into the influence of microstructure on the overall mechanical and brittle damage behavior of highly porous sound absorbing ceramics. I was able to contribute to the improvement of material strength by new material design while keeping the good sound absorption."

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."

Digimat-CAE is a tool that bridges the material data gap between composite material processing and the final performance of composite structural parts.
Digimat-CAE is the central tool for building coupled multi-scale analyses based on the manufacturing process. It centralizes the upstream and downstream interfaces for Digimat material models.
Local microstructure is taken into account and translated into a macroscopic material response. This results in a highly accurate prediction of the final performance of the composite part.
A multi-scale interface to integrate Material data into the design workflow:
Digimat-CAE offers GUI guidance for the set-up of integrative simulations and supports this approach via embedded Plug-Ins for GUI guidance in native FEA environments. Choices of Digimat multi-scale solution methods (Micro/Hybrid/Macro) allow to balance individually the need for accuracy and fast computational time.
- Micro: the most accurate solution that produces per phase results
- Hybrid: the solution that allows to obtain accurate prediction in a realistic industrial time frame - in average 10x quicker then Micro solution
