Digimat

Digimat is the multi-scale material modeling platform from Cadence (originally developed by e-Xstream engineering) that predicts mechanical, thermal, and electrical properties of composite and multi-phase materials from constituent properties and manufacturing process parameters. Unlike traditional FEA that relies on coupon-level test data for material cards, Digimat computes anisotropic material behavior from the microstructure — fiber orientation, fiber volume fraction, matrix properties, and manufacturing-induced effects — enabling accurate structural simulation of parts made from short-fiber reinforced plastics, continuous fiber composites, and additively manufactured materials.

The platform consists of specialized modules: Digimat-MF (mean-field homogenization for rapid material property prediction), Digimat-FE (representative volume element analysis for detailed microstructural investigation), Digimat-MX (material database and exchange), Digimat-MAP (mapping manufacturing process results to structural FEA mesh), and Digimat-AM (additive manufacturing material modeling). Digimat integrates with injection molding simulation (Moldflow, Moldex3D) to map fiber orientation from the manufacturing process into the structural FEA model, providing accurate anisotropic material properties for MSC Nastran and Marc analyses. This process-to-performance chain closes the loop between how a part is manufactured and how it will structurally perform.

For Indian automotive teams pursuing lightweighting with glass-fiber and carbon-fiber reinforced plastics, and aerospace organizations using continuous-fiber composites, Digimat replaces conservative isotropic material assumptions with physics-based anisotropic properties that reflect actual manufacturing conditions. GSAS provides Digimat licensing and application support for composite material modeling workflows.
