Product description

Digimat-FE is used to generate a realistic Representative Volume Element (RVE) of large variety of material microstructures (plastics, rubbers, metals, graphite, ...). Digimat-FE allows to describe the microstructure of your composite as well as the material properties of its constituents in order to generate the FE model of the composite’s RVE.

Digimat-FE uses Abaqus/CAE to generate the microstructure mesh and the actual finite element model that is then solved with Abaqus/Standard. Model post processing is then done in Abaqus/CAE and DIGIMAT.
