Process DescriptionProcess Description
Digimat is used across the automotive industry as a predictive software platform aimed at modeling the behavior of reinforced plastics parts, rubber parts, thermoplastic, elastomer parts and composite sandwich structures.

OEMs and 1st Tier Suppliers use Digimat to CAE interfaces to model the behavior of reinforced plastics used in exterior, interior and under the hood parts as a function of the local fiber orientation induced by the injection molding of the part.

Digimat is strongly coupled to major nonlinear FEA software (Nastran, Abaqus, ANSYS, LS-DYNA, Marc, PAM-CRASH and SAMCEF) and to Injection Molding software (Moldflow, SigmaSoft, Moldex3, REM3D).
Material Suppliers use Digimat to develop new material grade, to optimize the performance of their material offer and to support their end customers in choosing the optimal material for the target application performance.

  • Integrated crash pads allow weight and cost reductions. Setting the absorption behavior is only possible through a rigorous composite modeling. An integrated structural analysis with Digimat clearly reveals those benefits. Sandro Wartzack, Head of Simulation, Brose
