DIGIMAT software capabilities have been extended to model "nano-effects": interface between matrix and nano-filler, Size effect (absolute filler size, absolute coating/interface thickness), clustering and size distribution of clusters, interaction between filler particles, effective particle.

• Digimat-MF: by considering a material point in space and studying its properties, Digimat-MF, based on the semi-analytical Mean Field Homogenization theory, can be used as a "numerical material test lab". Using its advanced capabilities, not only can the user capture interphase nano-effects and model clustering but also study electron tunneling and percolation effects on the material conductivities (electrical, thermal). Thanks to its computational efficiency, it will also be your tool of choice to perform parametric studies.

• Digimat-FE: allows you to generate representative nano-structures and accurately model clustering and percolation. Coupled to a finite element solver (Abaqus, ANSYS, LS-DYNA, PAM-CRASH, SAMCEF), it also serves as a "numerical material test lab", and provides the user with very detailed information about the behavior of the material point under study. Fully integrated with Abaqus CAE, the meshing procedure and the model build-up are automated. Special post-processing tools are also available to the user to facilitate the statistical analysis of the results.

• Digimat to CAE: it couples the functionalities of Digimat-MF to FEA codes and enables the user to extend multi-scale material modeling from a particular material point to parts and structures.
