Digimat lets engineers do both micro- and macro-scale analyses of composites, predicting how they will perform and calculating their mechanical, thermal and electrical properties for use in all sorts of downstream FEA analyses.
Engineers typically start modeling by gathering material information and strand orientation data from Moldflow, 3D-Sigma, Moldex3D, Simpoe or another injection molding simulation solution, in the case of molded materials. Digimat-MAP calculates residual stresses and temperature from the injection molding mesh and defines an ideal structural FEA mesh. From here, many users go straight to FEA - MSC Nastran and Marc for instance, and other solvers that have direct interfaces. They may also use Digimat’s MF, MX, FE modules to look at test data for the composite and its constituents and look at promising material candidates. Users are able to see the tight link between part geometry, material flow during manufacturing and the resulting fiber orientation — and the effect all of this has on the part’s ultimate mechanical behavior.
